As Daboll has stated, they game plan each week based on the weaknesses of the opponent they face. The offense has to be multi-dimensional to stretch the field both vertically and horizontally, which requires all "types" of WRs, TEs, and RBs. Between Foster's deep threat and Allen's legs, I think the 15-20 yard midfield throws will be their bread and butter, and what matters there are guys who know how to find the soft spots in the zone. McKenzie and Zay should both work good there. They will definitely need another deep threat in addition to Foster, and it would certainly be great to have a young stud who is a multi-dimensional threat for Allen as well. I don't think they need to spend their R1 pick on finding him though...
