Here's the QBs who have won 3 or more:
Terry Bradshaw
Joe Montana
Troy Aikman
Tom Brady
I'd say that's a pretty good qualifier of talent.
here are some QBs that haven't won a single Super Bowl:
Dan Marino
Jim Kelly
Dan Fouts
Fran Tarkenton
These guys don't suck because their teams didn't win the Super Bowl do they? They are in the Hall of Fame, right?
4 times in 2006 alone. Go back and check the stats. The defense carried the offense that year. In four games, Manning more for over 300 yards once, and had 3 TDs vs. 7 interceptions. He was legitimately bad throughout those playoffs, but the rest of the team stepped up and compensated, and they won the SB.
During the 2006 regular season, the Colts defense sucked balls. Manning brought that team to the playoffs in the first place. I concede your point, though. The Colts D stepped up in the playoffs that year, and that's why the Colts won the Super Bowl. Brady has had the benefit of that happening a lot more than Manning, and that's a huge difference maker. Not having to constantly play from behind...not having to do everything for your team yourself, having someone else make up for your mistakes, etc.
And the Colts, in the playoffs, have won in spite of Manning as often as because of him. Those are just facts. There's nothing wrong with being a game manager in the playoffs. Roethlisberger is one too, and he and Brady have 5 SBs between them. Game managers win games.
Outside of 2006, this isn't true. His other wins in other years were all stellar performances. I'm telling you that the Colts never really had a good defense, and the 2006 season shows you what a good defense can do for your reputation. Now you can say "Manning won the Super Bowl," even though the defense played a huge role in it.
Yeah, there is nothing wrong with being a game manager. I agree with that, but when the rest of the team isn't picking up the slack, you have to be more than a game-manager at the QB position if you expect to win. In other words, the rest of your team has to be good if you are going to win with a game-manager. Otherwise, the QB has to take a lot more risks, which can lead to bigger mistakes. I'm not labeling Brady as a "game manager" per se here, only saying the Patriots won playoff games when that's exactly what he was and the defense won it for them, sometimes when he managed the game relatively poorly. Then people turn around and say "Brady won," which isn't entirely accurate. It's not untrue, but it's not entirely accurate. Winning a game doesn't mean you are skilled...it doesn't hurt, but that's not what that means.
I'm not saying that Brady isn't clutch either. I think it's obvious he is, but that's not what I'm talking about in this post. That's another story.
