You watch Welker and you see a guy look like he is about to lay him out and Welker somehow makes the guy almost bounce off him because he gets so low. Woodhead had some of that. Edelman doesn't have that because he is bigger. That was my point.
Welker in his prime probably would have done better. Welker of last year? I don't know. He looked to have lost a step even before the concussion. He looked more suited for the role that Denver used him as a second, third, or fourth option depending on the game, but never as Manning's primary receiver.
