One of the most tiresome narratives on the Seahawks and their current success is that any QB would love to play with this defense.
That statement isn't entirely untrue, but it's wrong nonetheless.
The benefit of having a great defense to any QB means that QB doesn't have long fields and isn't behind in many games. The problem saying any QB would be great on this team however, is laughable.
Could you imagine Peyton with this offensive line? He would have been carted off opening day.
That sounds pretty harsh towards the Hawks o-line, but the truth hurts. These guys are horrible at pass protection. We know it. The Hawks know it. But for some reason nobody else seems to understand this.
No other QB could survive the season with this offensive line. Which means that no other QB could take this team to back to back Super Bowls. Russ does this because he plays within the limits of his team on offense. He runs if he needs to. He gets down and protects himself when he needs to. He gets out of the collapsing pocket and keeps plays alive. And he's not afraid to fail, which means he bounces back when times are rough and doesn't get discouraged that he's not putting up obscene passing numbers.
He plays within himself.
So to answer your question. No. The Seahawks could not have gone to 2 Super Bowls with Flynn as the QB.
