Always thought of Welker as a possession reciever with some speed. His hands are what the Patriots are paying for. Not his height.
Gronk has the height, and is a favorite in the red zone, not Welker.
Big target, tiny defender's, makes a good matchup.
You a Pats fan? Don't want to know any insider secrets? OK. And yes, both AJ and LaMichael are 5'9" tall, but neither are CB's.
Runners, BarrySander's was 5'8". He did OK. LaDainianT also.
