Please don't bring rings into the convo. If that's the case, then Big Ben >> Manning, which isn't true. Manning never had the team (defense) that Brady or Ben had.
Let me just show you how important defense is:
Tom Brady had his 1st full season as a starting QB in 2002. Since then, the Pats have only had 2 seasons where they didnt have a Top 10 defense. 02 (they didnt make the playoffs) & 05 (they got eliminated in the 2nd round).
Big Ben has been in the NFL for 6 years. In 4 of his 6 years, the Steelers have had a Top 5 defense. The 2 years where they didnt have a Top 5 defense were 06 (they missed the playoffs) & 09 (they might not make the playoffs).
Peyton Manning has been in the NFL for 12 years. Since then, the Colts have only had 1 year where they had a Top 10 defense. That was in 06, the year they won the Super Bowl.
Concidence? I think not!!! There's a reason why they say DEFENSE WINS CHAMPIONSHIPS.
Brady and Ben always had a good/great defense, while Manning has always had a mediocre defense. Hence why he has less rings than Brady & Ben.
