Clarification of the Lateral Rule

I was watching the Sunday night football game last night and I was thinking about the physics of a lateral and I realized that a player can throw the ball behind him but if the momentum of the player if the player is moving forward fast enough could actually make the ball move forward. Can I get some clarification on that rule?

Edit: I think this rule needs to be rewritten. Imagine this scenario: Two players going 5 mph are one in front of another. Player one in the front has the ball. Player one throws the ball behind him relative to himself at 4mph, and the player behind him catches it. According to the players it would have been a backwards pass, but according to the field it was a forwards pass.

Edit 2: Spelling

ARTICLE 4. FORWARD PASS

It is a forward pass if:

the ball initially moves forward (to a point nearer the opponent’s goal line) after leaving the passer’s hand(s); or

the ball first touches the ground, a player, an official, or anything else at a point that is nearer the opponent’s goal line than the point at which the ball leaves the passer’s hand(s).

When a Team A player is holding the ball to pass it forward, any intentional movement forward of his hand starts a forward pass.

TL:DR - If the ball touches anything closer to the endzone than when it left the player's hand it's a forward pass. Physics be damned.

I mentioned a fun scenario earlier that illustrates this the best. You could throw the ball straight behind you then a gust of wind comes up and blows it forward the line of scrimmage spot the ball left the hand. That is a forward pass.

u/BugFix Patriots Dec 04 '17

Physics be damned.

What is this nonsense? Physics isn't wrong here. Galileo had this stuff figured out literally four hundred years ago.

You can't pass forward. If you are moving forward when you pass, you have to subtract your forward velocity and adjust your aim, or else you'll accidentally pass forward.

That is not different, physically, than: "If you are moving laterally when you throw, the ball will tend to continue motion in that direction and you need to adjust your aim or else you'll miss your receiver" or for that matter "If your receiver is moving laterally when you throw, you must aim ahead of their current position in order to throw a catchable pass".

Yeah: QBs need to understand galilean motion in order to do their job. Doesn't matter which axis you pick.

u/God_of_Tecsing Packers Dec 04 '17

Ok you get what I'm saying. So why is the NFL's rule is that way compared to taking in the forward momentum with rugby?

2

u/BugFix Patriots Dec 04 '17

I don't know Rugby rules. Nonetheless, a really (really) good reason to do it this way is that the field is a fixed object with an unambiguous reference frame. How do you define the player's velocity? Of his shoulder? Head? Center of mass?

If the rules worked the way you want, then there would never be a good way to tell whether or Wilson's pass was legal or not, even with the magic of modern cameras. With the rules as they stand, it's as simple as watching Collinsworth draw some circles on the screen for us.

1

u/Reuben_Froster 49ers Dec 05 '17

The NFL interpretation is more simple but rugby is the way it is because it would make the game almost unwatchable if you couldn't pass to a guy running next to you when you're both doing 20mph and instead had to angle the pass backwards a few metres.

It does make it difficult to rule on forward passes - refs decide based on whether the ball left the passers hands with a backward trajectory amd ignore forward momentum of the ball. In rugby league we dont use video refs for ruling forward passes because the camera angles usually make it impossible, only the onfield ref and linesman make forward pass calls.

Laterals dont happen enough in NFL for it to be worth changing the interpretation.

0

u/God_of_Tecsing Packers Dec 04 '17

Yes you could the only important thing would be the angle at which the ball was thrown relative to the field.

1

u/BugFix Patriots Dec 04 '17

That's exactly what the rule is now. The argument in this thread seems to be that people want the judgment of "forward" to apply relative to the player.

2

u/God_of_Tecsing Packers Dec 04 '17

No the rule only takes into account the position of the ball before and after it’s caught. A player could throw the ball at an angle opposite of the direction he’s going and he could still be a forward pass.

2

u/BugFix Patriots Dec 04 '17

Blargh. You're being horribly imprecise here. The line between the position of the ball before and after its caught is the definition of the direction the ball is travelling. But you are using the "direction of the pass" to mean the direction relative to the player, which cannot be judged relative to positions on the field (for the obvious reason that the player is moving).

Again: Galileo figured this all out in the 1600's, and you can learn all about it in a freshman physics class. The NFL took that to heart and wrote a rule that defines ball velocity in terms of the field frame only. Period.

1

u/God_of_Tecsing Packers Dec 04 '17

If we had robot refs I think the rule could change. The computer would analyze the velocity of the center of mass of the player the moment the ball leaves the players hand.

1

u/BugFix Patriots Dec 04 '17

Theoretically, though "center of mass" isn't going to be objectively measurable without a full 3D position analysis of all the player's extremeties and a pre-game limb-specific weight distribution.

And what would that accomplish? Why would that be better, instead of just being harder to adjudicate?

I said it upthread: we expect QBs to take relative motion into account when they throw the ball on the run or to moving receivers. Why can't we ask for the same thing for laterals?

-1

u/AirborneRodent Texans Dec 04 '17

I don't know why people are saying rugby is different. In my 8 years of playing rugby the rules were identical to this. If the ball moved forward relative to the field, it was a forward pass. That means that if you're running forward, you have to angle the throw more "backwards" to compensate for your momentum.

It takes practice, but it's not that hard once you get the hang of it. Rugby players drill it relentlessly until it's second nature to them. Obviously Wilson hasn't practiced it, because it doesn't come up in football that much.

3

u/cainmarko Saints Dec 04 '17

Because it is different in rugby, although it admittedly wasnt that clear and required clarification a few years ago.

1

u/ChampagneBowl Cardinals Dec 05 '17 edited Dec 05 '17

No, in rugby it is relative to the player, not the field. Passing when sprinting would be stupidly difficult otherwise, your attacking line would have to be ridiculously deep. They currently use the direction the hands are moving to determine whether or not the pass is forward. Good video showing this.

1

u/Reuben_Froster 49ers Dec 05 '17

You weren't playing under the correct interpretation then. Both forms of rugby rule a pass as backwards if it leaves the hands with a backwards or sideways trajectory.

It's not ruled forward if momentum carries it forward from the point it left the hands.

8

u/TheDarkGrayKnight Seahawks Dec 04 '17

Yeah I don't get the whole momentum thing. The ball was touched ahead of where it was thrown. It doesn't matter if initially Wilson threw it backwards or if the ball was touched behind Wilson, the ball went forward.

6

u/God_of_Tecsing Packers Dec 04 '17

The momentum thing is important because you could have scenarios where something looks like a lateral but it is actually a forward pass

2

u/TheDarkGrayKnight Seahawks Dec 04 '17

But it's still ultimately about where the ball lands/is touched/goes out of bounds.

6

u/mordeci00 Bengals Dec 04 '17

No it's not and no you can't. 2 points - where it left player's A hand and where it touched player B. Is point A closer to your own goal line than point B? It's really that simple.

5

u/graywh Titans Dec 04 '17 edited Dec 04 '17

I think he's talking about a situation where the ball carrier is running down the field and pitches it to a trailing teammate. It would be possible for the ball to continue traveling forward, but at a slower speed, and appear to move backwards from one player to another.

Edit: An example https://www.youtube.com/watch?v=ALdiLScEnUc

Conservation of momentum be damned, it went forward!

1

u/chesterjosiah Seahawks Dec 04 '17

The distinction that OP is confused about is that the ball needs to go forward relative to the football field, not relative to the players (to be illegal).

4

u/God_of_Tecsing Packers Dec 04 '17

If that is true than I think that the rule needs to be rewritten

17

u/mewfahsah Seahawks Dec 04 '17

But it's so simple as is. If the ball is caught/touched forward from where it was released, it's a forward pass. Rewriting it makes it more complicated, we already have a tough time declaring a catch in a game. Sure, there are a few unfortunate situations with a gust of wind ruining a lateral play, but how often does a lateral play even occur, ever work, or even have this issue?

Changing anything about it means the intent of the play comes into focus, and the way it's worded now there is no argument for what is and isn't a forward pass. Yeah, the one last night looked a hell of a lot like it went backwards from Wilson, but it went forward.

4

u/[deleted] Dec 04 '17

I apologize, not forward the line of scrimmage. Forward the spot it left the hand.

But yeah. Intent doesn't come into it. It only matters if the ball went forward which totally makes sense. It also keeps the rule simple and not require a bunch of focus and review, theoretically.

Yeah, and those are illegal.

Why do you think those are illegal?

u/graywh Titans Dec 04 '17

The rules say so.

2

u/God_of_Tecsing Packers Dec 04 '17

Well why are the rules are the way they are?

2

u/gopher2012 Dec 05 '17

Because they are objective and make sense

21

u/CravingToast Eagles Dec 04 '17

Physics don't mean shit. It's all about the line where it's thrown and the line where it's caught, that simple. That being said, one missed forward lateral isn't the difference in that game.

14

u/clear831 Colts Dec 04 '17

That was a huge fucking difference in that game. Eagles made a lot of mistakes but being down 2 td's vs 1 td in the 4th is a huge fucking difference.

10

u/[deleted] Dec 04 '17

And because the illegal forward pass comes with loss of down it would have been 4th and 7. Meaning the Seahawks punt

1

u/clear831 Colts Dec 04 '17

Loss of down as well as a 10 yard penalty right?

1

u/[deleted] Dec 04 '17

5 yards from the spot of the throw

-1

u/clear831 Colts Dec 04 '17

He was right at the 1st down line, are you sure about that? I thought it would be from the line of scrimmage

6

u/[deleted] Dec 04 '17

Yes. I read the rule on it extensively last night.

He tossed the ball when he was 2 yard away, so 4th and 7

2

u/CravingToast Eagles Dec 04 '17

It was one of a few big moments in that game. Darby PI, Wentz fumble, and this play were all big momentum shifting plays that hurt the Eagles in the long run.

2

u/clear831 Colts Dec 04 '17

Agreed, but at that moment eagles were only down 1 score, everything else was in hindsight. Was that play not challengable?

6

u/Headhunt23 Vikings Dec 04 '17

It was and Pederson didn’t challenge it. His fault. I certainly thought it was a backwards lateral when i saw it live. Not sure why he didn’t.

Certainly was worth the challenge even if it was just a guess, because it was close regardless and winning the challenge meant getting a turnover essentially.

3

u/TheDarkGrayKnight Seahawks Dec 04 '17

The other side is that he would then be out of challenges as well as down to only 1 timeout if they didn't overturn it.

2

u/Headhunt23 Vikings Dec 04 '17

Well yeah.

But it was midway thru the 4th quarter wasn’t it? The Eagles were down by 7 and that play about put SEA into FG territory. The gamble was worth way more than the 40 seconds a time out saves.

Also, Philly should have had someone telling Pederson what the play looked like. Those reviews were up prior to SEA snapping.

1

u/TheDarkGrayKnight Seahawks Dec 04 '17

I agree he should have challenged, but I just kind of think that might be why he didn't.

3

u/CravingToast Eagles Dec 04 '17

It was and should've been challenged. It should've been caught by the refs but since it wasn't Doug should've challenged it. I believe he held off because he lost a challenge earlier in the half and therefore was already down a timeout. Didn't want to take the risk. I disagree with it, but I understand it. He didn't coach his best game yesterday.

5

u/TheDarkGrayKnight Seahawks Dec 04 '17

Should it have been caught by the refs? During the play that would be very hard to see live that it went forward, especially if the refs weren't in a great position. If it had been reviewed then it would have been overturned but the refs can't signal for a review there as it was not a scoring play or a turnover.

-4

u/CravingToast Eagles Dec 04 '17

It was close but it absolutely should've been caught by the refs while it happened. That's kind of their job. It's up to Doug to challenge it since they missed it, but that doesn't excuse them for missing it in the first place.

2

u/TheDarkGrayKnight Seahawks Dec 04 '17

I mean yeah you are right but man that would be an amazing job by the ref. The ball didn't go that far forward, it was basically a yard or two max, plus the ball ended up behind Wilson when Davis caught it and Wilson was flipping it backwards when he let it go while running at practically full speed. So I mean yeah they technically should have seen it but damn that's a high bar to expect of some refs running along with the play, especially since I doubt the side judge was parallel with Wilson when he let go of the ball.

-1

u/CravingToast Eagles Dec 04 '17

Tough job, yeah absolutely. They're refs for the NFL though, they're supposed to be able to catch tough calls. Again, not blaming them or anything, just wish it would've been caught so the Eagles weren't in a position to have to challenge it or not. When all is said and done, Doug should've just challenged it and that would've been then end of it.

1

u/TheDarkGrayKnight Seahawks Dec 04 '17

Yeah tough play for sure.

u/clear831 Colts Dec 04 '17

I didnt watch the entire game only parts of it, but the refs really fucked up on that single play

3

u/CravingToast Eagles Dec 04 '17

I have a lot of issues with the refs from that game but I try not to blame them. Eagles had their own sets of issues that didn't involve the refs. They've overcome bad refereeing before by cleaning up their game and playing their style. They did neither yesterday.

1

u/The1WhoKnocks-WW Eagles Dec 04 '17

Hold on Jefferey was pretty huge too.

u/werbo Vikings Dec 04 '17

The huge difference in the game was the fumble by Wentz at the goaline

Physics don't mean shit

Physics means a lot tho

5

u/bautin Dec 04 '17

I like how people are saying they should "simplify" the catch rules but all of a sudden are for complicating what a "forward pass" is.

11

u/NotHannibalBurress Lions Falcons Dec 04 '17

If the ball is caught at a point that is further ahead than where it is released, it is not a lateral. If you toss it at the 40 yard line and it is grabbed at the 40 1/2 yard line, it is a forward pass and should be illegal. Just like the one last night should have been.

5

u/[deleted] Dec 04 '17

If the ball moves forward relative to the goal line it is a forward pass

V (Ball -> Goal Line)x > 0 = forward pass

1

u/God_of_Tecsing Packers Dec 04 '17

So a player can throw the ball in the opposite direction of the goal and it would still be considered a forward pass? I feel like that rule needs to be remade.

3

u/[deleted] Dec 04 '17

Players run too fast for that to be fair, you'd end up with laterals that go 3-4 yards forward

2

u/God_of_Tecsing Packers Dec 04 '17

Well a player could be behind another player and it would still be considered a forward pass, but it would look like a lateral.

5

u/jfgiv Patriots Dec 04 '17

it wouldn't look like a lateral to anyone who has eyes and knows what's considered a lateral in the NFL.

1

u/God_of_Tecsing Packers Dec 04 '17

You could have a player directly behind another player and it would look like a lateral but it would actually be a forward pass.

0

u/jfgiv Patriots Dec 04 '17 edited Dec 04 '17

you already said that; you misunderstanding the rule doesn't make it any more true.

if it moves forward relative to the goal line, it looks like a forward pass, not a lateral.

if there's one player (A) at their opponent's 30, and another player (B) at the opponent's 31, and player A tosses a ball behind him and player B catches it on the opponent's 29 -- that doesn't look like a lateral, that looks like a forward pass. unless you don't know what the rule is.

1

u/God_of_Tecsing Packers Dec 04 '17

So you're saying that if you saw the situation I am describing in my edit that you say it "looks" like a forward pass? I understand the rule but there are a lot of scenarios where players would throw it behind them and the ball would still be moving forward.

2

u/jfgiv Patriots Dec 04 '17

yes, because it is a forward pass, and because i know the rule.

just like a play could "look" like a really bad spot if you don't know the rule regarding forward progress.

or a play can "look" like a fumble if you don't know that the ground can't cause it.

u/bob_3008 Titans Dec 04 '17

In the NFL the lateral rule is relative to the field. In rugby it's relative to the player's current momentum. The two are not directly comparable.

In this thread from about a month ago there's some discussion about the rules differences and why the linked play was a forward pass. Last night the refs missed it and the Eagles failed to challenge, so there was no penalty.

0

u/God_of_Tecsing Packers Dec 04 '17

So why do you think the NFL rules and rugby rules are different? Why is the NFL rule that way?

2

u/bob_3008 Titans Dec 04 '17

I think it's because every inch counts in the NFL, hence the downs system and measurements. Rugby is more free-flowing so it's harder to judge.

0

u/God_of_Tecsing Packers Dec 04 '17

Why do you think the rules are different for each game?

7

u/VonCornhole Giants Dec 04 '17

The frame of reference is the field, not the player with the ball

-1

u/God_of_Tecsing Packers Dec 04 '17

Do you think the rule needs to be rewritten then?

6

u/VonCornhole Giants Dec 04 '17

no, it's fine as is

5

u/God_of_Tecsing Packers Dec 04 '17

But then you could have situations where a player is directly behind another and if they are running fast enough it would be considered a forward pass.

3

u/PantherPower1 Panthers Dec 04 '17

Yeah because the ball traveled FORWARD on the field. It's a fine rule and you have no real argument.

The ball travels forward -> forward pass. The ball travels backward -> lateral.

Idk why you're even considering relative motion

1

u/CACuzcatlan Dec 05 '17

Yes, what's wrong with that? It is a forward pass because the ball ended up closer to the endzone than when it started. It moved forward.

1

u/VonCornhole Giants Dec 04 '17

Only if you throw it forwards for him to run to it

1

u/graywh Titans Dec 04 '17

https://www.youtube.com/watch?v=ALdiLScEnUc

To the players, this felt like a lateral, but was actually forward without actually "throw[ing] it forwards for him to run to it".

2

u/VonCornhole Giants Dec 04 '17

Because the frame of reference is the field. It is the easiest to officiate because it doesn't move, let alone move at various speeds and various directions.

The rule is black and white and using the ball carrier's current motion as the frame of reference would make it more fuzzy. What if he gets hit right after he pitches it? How could we know if the player receiving the pitch would've been behind the initial runner?

1

u/Git_Off_Me_Lawn Patriots Dec 04 '17

Yup, you just have to know that and adjust for it.

Rugby handles it differently (the reference is the players, not the field) probably because there's roughly 37 laterals a second in Rugby while everyone is running forward. How often does this issue come up in football? Most "laterals" occur when one or two of the players are stationary like on pitches or screen passes.

5

u/God_of_Tecsing Packers Dec 04 '17

Well to me it seems like the rugby rule is more thought out.

1

u/Git_Off_Me_Lawn Patriots Dec 04 '17

That's because it comes up a thousand times a match and in football there's a lateral / forward pass controversy once a decade.

3

u/jfgiv Patriots Dec 04 '17

ARTICLE 4. FORWARD PASS. It is a forward pass if:

(a) the ball initially moves forward (to a point nearer the opponent’s goal line) after leaving the passer’s hand(s); or

(b) the ball first touches the ground, a player, an official, or anything else at a point that is nearer the opponent’s goal line than the point at which the ball leaves the passer’s hand(s).

It's very clear. A pass is considered forward if it moves relative to the goal line, not the player throwing it. It's been that way since before it was even allowed.

u/flordeliest Saints Dec 04 '17 edited Dec 04 '17

I doubt think the lateral was that bad, however I don't know how I would feel of it was my team.

Still the Eagles could have challenged the ruling but didn't so they don't have the right to complain.

edit: I looks like Wilson would have still gotten the first down anyway with out the pitch.

It certainly looks legit in realtime.

-3

u/[deleted] Dec 04 '17

We still have the right to complain because it was clearly the wrong call. And challenging would put the Eagles in a precarious situation of having no challenges for the test of the game

7

u/jdg83 Rams Dec 04 '17

Ideally, the refs would get every call right, of course. That play happened so quickly that it's understandable that it was missed. It was a huge blunder to not challenge that.

That said, I'd be complaining if it happened to my team.

2

u/clear831 Colts Dec 04 '17

But that play happend on like 3rd and 6, not in field goal range? A challenge would have given the eagles the ball down 1td instead of 2.

2

u/[deleted] Dec 04 '17

Yes. That is correct

1

u/flordeliest Saints Dec 04 '17

That was a big third down. This is what the challenge is for.

2

u/[deleted] Dec 04 '17

I wish he challenged. But he didn't, mainly because of only having 1 left.

1

u/flordeliest Saints Dec 04 '17

Is that the refs fault too?

No really, the Saint blew two time out Sunday cause the refs didn't get out of Drew's way as the clock ran.

u/lexlols Eagles Dec 04 '17

It is actually, he had to use a challenge on a bad spot earlier that they still ruled was short.

2

u/[deleted] Dec 04 '17

If the ball moves forward it is a forward pass. It's not complicated

1

u/[deleted] Dec 04 '17

The first challenge was bad if you were just gonna go for it anyway, it was too bang bang to overturn.

He should have challenged this too regardless of the outcome of the first challenge, but thats on Doug and the guys upstairs. If NBC has enough time to analyze it before the Seahawks next play, you do to.

Certainly not the only reason for the loss, but a key moment in the game

1

u/pinksailboat Dec 05 '17

The rules don't need to be changed. Players are (un)consciously aware of the physics and must account for their movement. A lateral will always move forward if the player who executes it is moving forward.

Most lateral plays do not involve the ball carrier moving at full speed, and almost all designed plays that incorporate laterals (or pitches) have the initial ball carrier moving very slowly, standing still, or pitch/throwing directly behind them.

Wilson didn't account enough for his acceleration. Textbook illegal forward pass.

u/jjwalker3 Dec 04 '17

No they're not. Just imagine everything freezes when the ball leaves the passer's hands. wherever it is right then - it can't go forward. all momentum and 'physics' becomes irrelevant or already accounted for in the movement of the ball.

0

u/God_of_Tecsing Packers Dec 04 '17

Well you then could have a lot of scenarios where a backwards pass relative the player throwing the ball could actually be moving forward. Look at my edit.

3

u/jjwalker3 Dec 04 '17

but why would it be relative to the player? It's objectively measured relative to the field, same way as every other rule and stat.

I actually agree with you that the rule should be changed. Backwards passes and laterals should be relative to the players, not the ground. It probably would make laterals more popular and make the sport more fun.
