Well lets look at the other side of the coin.
The Patriots won without Brady because of having a great team.
The Colts without Manning were not near as talented as the Patriots were.
Manning was a generational QB and had the capabilities to carry a team.
That is not the norm.
Teams have won the super bowl with QBs who are not even considered that good.
You speak of Manning- Just how good was Manning when the Bronco's won the super bowl. You honestly think he was good enough to carry that Bronco's team to the super bowl? He was down to a game manager at that point in his career.
Yes QBs get the glory because of their position but they couldn't do anything without the team around them.
It was not a stupid statement IMO.
