Bah, I'd move my post here if I knew how to without causing problems.
I'll just copy it in here.
I don't know if I agree there. Manning is a good QB, but even when Harrison isn't catching the ball he's important. He's going to draw the #1 CB for the opposition and probably one or two other guys when they are playing zone. This leaves Wayne, Stokely, whoever in single coverage that Manning reads and reacts to. Without Marv there, the defenses would be able to play more straight up defense and give Peyton some headaches in finding an open guy.
If anyone goes, I'd say it's the Edge.
