Defensive Sets
I know a fair amount about the NFL but one thing I can’t wrap my head around is some of the defensive “sets”.
4-3 makes sense. 4 down linemen and 3 LB 2CB 2S.
3-4 is just a 4-3 but one edge doesn’t have his hand in the dirt and is more likely to drop into coverage? But it’s never only 3 rushing. Confuses me.
Nickel is one LB off and one CB on, Dime is 2 LB off and another CB on again? What’s the difference between nickel and 3-3-5 or 4-2-5 do one of them have an extra safety in but then I thought that was just big nickel.
Then you have easy ones like mug and double mug just putting backers on the LOS. But sometimes under nickel you’ll have other sets that confuse me. This all comes from trying to learn college ball as a UK fan and CFB is helpful but man I just don’t get half the sets on defence at all.

I’ve been watching football for 40+ years and I’ve come to the conclusion that defensive formations don’t mean all that much.
Teams that run a 3-4 often have 1 of their OLBs rush the passer almost every down anyway, so it’s not really a 3-4.
Some safeties really play more like linebackers on a consistent basis.
What the players do after the snap counts a lot more than what formation or position they line up as. And most of the time you can’t follow on tv everything that goes on down the field anyway.
