Yeah and if he was a little ahead of the game with the gloves it's more than made up for by the fact that you can't tee off on receivers OR quarterbacks the way you could in Jerry's day.
He had plenty of advantages outside of that -- let's start with the all-star fantasy team he was on.
The 49ers of the 80s and later the Cowboys of the early 90's are *the* reason the NFL put an end to the 2 team arms race of super powers every year where Deion, Charles Haley etc just traded uniforms between those 2 teams and implemented the salary cap. Those franchises could never come close to existing in today's NFL, and to the league's credit they understood the shit show MLB was becoming and saw the correlation between its declining numbers and lack of competitiveness and didn't want the NFL to follow suit. Best decision the NFL ever made.
I mean, kudos to the Debartolo's and Jone's families for leveraging every advantage they had at their disposal, but they were calling the NFC Championship game in those days the Super Bowl since it was those teams and to a lesser degree the Giants. If you were alive then you had to watch/listen to Pat Sumerall dodge huge loads of Madden jizz every time those two teams played and had to listen for 3 hours how nobody was close to them as the two best teams -- yea no shit.
You also have to give Bill Walsh a fuckton, a metric fuckton of credit. Dude was a visionary and doing the 5d chess shit way back when everyone had 3 hulking linebackers (or 4) to stop the run and he realized you could make it a liability for them and just use the West Coast offense as a run game -- teams had no idea how to defend it. I mean, Dick Lebeau had to design an entirely new defensive scheme in the zone blitz to stop it (to his credit as well). That 49ers coaching tree under Walsh is unreal.
Rice is the GOAT, but nobody playing in the NFL as a WR could have asked for a better set of circumstances to be a part of. That's why Barry Sanders is my personal GOAT player, the Lions were basically like "well we suck donkey dick just give #20 the ball and hope he can do something, otherwise fuck it". Dude somehow performed feats of magic on Sundays against stacked boxes that knew the trick ahead of time.
