The WR concern follows the development curve for Tate and Price, both of whom have the size and speed to play outside the numbers and run intermediate and deep routes. Tate is now entering his sophomore season for all practical purposes and Price is essentially a rookie. Both need extra time with Tommy, the question then becomes how much time will be available around rehab and with Tommy's partnership with Welker?
While were at it I would add Edelman as a potential outside the numbers intermediate route runner (similar to Branch) with whom Tommy could use more repetitions. We must also consider how Hernandez fits into that equation with his hybrid skill set.
As of the end of 2010, Tommy is tight with Welker and Branch, his earlier rapport with Hernandez seems to have slipped, whether as a function of defenses adjusting or an issue between the two I couldn't say. Tommy and Tate are not yet on the same page, and it's reasonable to project that shortfall to Price too.
NE currently has in development four youngsters who have the potential to run the intermediate and deep passing routes. They have a lot to learn and there is a significant burden on Tommy to bring them along. I have no objection to drafting another WR, certainly Julio Jones deserves consideration in round one (I suspect A.J. Green will be gone before #17), but the rest of the field are less certain and better values later. Myself, I'd love to see a big possession receiver like Austin Pettis who will fight for the ball in the middle of the field, more of a chain mover than a game breaker. I still miss David Givens and hope to see young Price fill that void for me.
