I'm on board with the too much emphasis on the pros argument. College football isn't the end of football, and yes, Moss and Rice (and others on the lists) were among the GOATs, but not in college they weren't. So if this is a college list, then it should be measured on college football metrics, which basically means major college football metrics, e.g., P5+ND, and the other major independents of years past. Jim Brown is relegated to the honorable mention list for his lack of playing time; if he isn't higher, then surely Rice and Moss shouldn't be as high.
Barry Sanders is another one I question. Yes, great college player, yes one of the GOATs, but more than Archie Griffin, the only two-time Heisman winner?
RB is a tough category as there are a lot of great players with impressive resumes. I could see moving Griffin up, and removing Bo Jackson from the 2nd team.
Do we care if they played through their senior year? For a college list, that should help, not hurt, their case? Tony Dorsett was a Heisman winner and led Pittsburgh (!) to a national championship (I know, Pittsburgh claims 9, but '76 is the only modern-ish one). Anthony Thompson has a decent argument; Charles White, Ricky Williams?
And that sets aside the old guys, like Glen Davis, or Doak Walker.
