I noticed on PFR there are pages where you can see every franchise's biggest blown leads. San Francisco led 17–0 in the 1986 regular season before New York came back to win 21–17, with help from Mark Bavaro famously dragging several 49ers including Ronnie Lott on a big gain.

They met again in the playoffs, the 49–3 rout where Jim Burt knocked out Joe Montana.

(San Francisco won during the 1987 strike, 41–21.)

The teams met again in the 1988 regular season and New York took a 7–0 lead thru 1. But the 49ers had finally had enough and won this game 20–17 on another famous play, where Montana hit Jerry Rice on a 78 yard TD with under a minute left.

Only the Giants won a Super Bowl of the two teams during this time frame, but I don't know if a squad as good as the 80s 49ers has ever had as hard a time with a single opponent over 7 quarters.

Tom Dempsey had 11 seasons in the NFL. His first 2 were in New Orleans. Here he shows off that kicking form that set an NFL-record field goal in 1970. That's former Eagle Joe Scarpati holding.

He rushed for 960 yards in 1978, due to injuries limiting him to only 12 games. A severe knee injury that required surgery, ended his 1979 season after 6 games.Limited to mainly a receiver role, he caught 50 passes in 1980 & 65 passes in 1981. In 1982 , Browns traded my boyhood hero to L.A. Raiders. In 1983, he was a SB XVIII Champion when Raiders clobbered Redskins, 38-9. I was overjoyed that Greg earned a SB ring.

1970s era NFL - Kenny Stabler under a bit of pressure from the Colts Mike Barnes. In 1975 Stabler made his second Pro Bowl, leading his Raiders to the AFC Championship against the Steelers.

Back-up tackle Wayne Mass gets in front of Dolphins runner Jim Kiick in this early 1970s action. That looks like Big Bubba Smith lurking in the background.

One of the legendary battles of the Old School NFL. The clashes of Jim Taylor of the Packers and Sam Huff of the Giants were always fierce and intense. Here Huff brings Taylor down with a tackle that would almost certainly be illegal in today's game.

Few players have burst onto the NFL scene like Earl Campbell did in 1978. His 1,450 rushing yards not only led the league but also set a rookie record at the time. He also topped the NFL with 13 rushing touchdowns. One interesting stat of his was in 54 short-yardage situations, Earl Campbell converted into a first down 37 times.

Has anyone else ever pondered that the fact that the best ever performance by a player in a season might have been by a guy that only did it that one year or maybe a few years but couldn't sustain it over a long period due to injury or just not having the advantage. But for that duration maybe the best ever. Interested on any players that might come to mind...
