You've gotta be kidding me, Rodgers was stuck with Mike McCarthy who is one of the worst head coaches with the worst coaching tree of anyone who has head coached that long. Rodgers got 2 good seasons out of Driver, 3 out of Jennings, Jordy Nelson for 7 years, and Davante Adams now. Rodgers never had much of anything at tight end. Brady had the best tight end ever for 10 seasons, he had Troy Brown for 3 years, Hernandez for 3 years, Welker for 6 years, Edelman for 6 years, the second best receiver of all-time for 3 years...At a minimum Brady had 2 Hall of famers to throw to, Rodgers had none. Out of those top targets to throw to for Brady it's a combined 7 first team all-pro seasons and 2 second team all pro seasons. For top targets for Rodgers to throw to it's 1 combined first team all-pro season.
Biggest difference in terms of winning is Brady had the best coaching of all-time and some of the best defenses in the league over his 20 years, Rodgers had bad coaching and mediocre to horrible defenses.
