Look, I can't stand him. I think he's a cheat and a liar, and the NFL has altered the rules for him for a long time. And of course, greatness can always be debated (especially between eras). If you just look at the numbers though, Montana, etc., aren't close.
Joe didn't play until he was 43 either. Also the game has completely changed since Joe's time. I mean, Joe never broke 4,000 passing yards and Kirk Cousins has done it 5 out of 6 years as a full time starter. You gonna say Kirk is better than Montana?
