The key will be the pass defense. The Broncos did exactly what everyone on this board wants to do. Shut down the run game, including Wilson running and make him beat you throwing in the pocket.
And you know what, Wilson did. He threw the ball to Baldwin, Kearse and Locket and put up enough points to win the game. You watch that game and you understand why they went with those receivers in 2014.
The Seahawks are a really good team and I think the fans (but not the Pats!) and under valuing Wilson and the Seahawks passing game. The receivers win the one on one match ups and make plays when they need to. Seattle was in lots of 3rd and long situations in the Superbowl and came through in the clutch.
The Pats have the personal to do what Denver could not do. Control the running game and manage the passing game of Seattle.
As for the offense, Manning missed lots of play in that game. The only guy that showed up was Welker and Manning only went to him at the end. They also ran these stupid crossing routes that set them up for big hits. The pats don't do that and I think Brady will have lot of out passes and will try to limit the big hits.
