BUT, as I have said ad nauseum, football is less dependant on individual "stars" than any other team sport. It is a TEAM game, and having a great QB is nice, but a lot of "great QB's don't get to hoist Lombardi's very often. It is HARD to even get to the superbowl, let alone win one. Brady was STILL one of the best QB's in the game and the Pats were one of the best teams, when he went TEN years without winning one
Just think about the vagaries of the game. Mahomes might not have even gotten to the game if not for a roughing call at the end of the AFCCG. Brady might have had more rings if not for about a dozen non calls on the helmet catch play. Officials are not the only random factor that decides games, great plays by individuals, good and bad calls, adjustments, time management, etc all factor into the randomness of the game..
