I think the stumbling block here is the compensation.
If your the Pats it would seem to have to be significantly less then the 3 you recieved for Moss. (5th, 6th, or 7th)
If your the seahawks why do you give away a player who has been producing this year for nothing. (is a 5th,6th, or 7th enough)
I think it would be nice to add depth to the position but I like the trio of Welker, Tate, and Edelman. With Price still learning and being the key back up. I would say Welker, Tate, and Edelman compare to Brown, Branch, and Givens but if you want to give a nod to the old school you have to give the nod to the new school TEs.
