Geeze guys, the issue is right in front of our faces.
The guys today have every advantage of early nutrition, training, camps, S&C, far more focus on HS athletics, etc. etc, etc. My daughter's HS even has a full time trainer on staff for athletes. How many had those even in the 90's?
You have to judge based on talent level and the changes in the game. The game today favors offense FAR more than it did in 1962. The reason is simple... TV. People don't tune in to watch a defensive struggle, they love offense. The game has been changed. We have to normalize for that.
To those who question if a "marginal" athlete could survive in today's environment of "super athletes," I gave you David Greene - UGAg's winningest QB, and far less athletic than Lothridge.
To those who question what Lothridge (6'2" 195) would have done in the same Fridge offense that Hamilton played in, I give you George Godsey (6'2" 205). Lothridge was much more agile and mobile than Godsey, with easily as strong an arm, yet Godsey is 3rd in all-time passing yardage at GA Tech with (6,137 yards). You put Billy Lothridge in charge of those 2000-01 teams and watch what his stats would have been.
To those who wonder what Hamilton would have done on a team in 1960, I give you Fran Tarkenton. Very similar type player. Joe would have excelled on his talent in that era, too.
Talent translated to different eras, but stats don't. We need to grasp this simple fact of athletics.
