College takes a lot of thought because the numbers are all over the place. A guy wearing number 5 can play any position on defense or be a QB, WR, or RB on offense. There are also a lot of great players from the past that I have no idea what number they were in college.
In the NFL #12 is an iconic number for QB’s. Brady, Bradshaw, Staubach, Griese, Namath, Rodgers, Stabler, etc. That’s 16 Super Bowl wins right there. And that doesn’t include Jim Kelly and his 4 appearances and HOF credentials.
There was a period in the NFL record books where the top 3 all time NFL rushers all wore #32. Jim Brown, Franco Harris, OJ Simpson.
Idk. Tough question. That’s a pretty good list of college players wearing number 20.
