Zay can't separate well enough to be a #1 or #2... I'd replace him with a kid like Greg Dortch from Wake Forest.
Foster is speedy, and versatile if he can consistently catch the ball, so he stays... I don't know much about Duke, but I require more than CFL-cred at WR to comfortable with hanging onto him... Hakeem Butler is a guy I like as a big, physical, threat... Reminds me of Plaxico to tell you the truth... I feel like Isabella will either be a Chief or a Cheat... Get him in space and it's first-and-goal every time. -Gotta have an accurate QB though... TJ Hock would be wonderful if the bills don't target a TE in free agency... I didn't see much scheming go into our offense last season. That has to change in order to use weapons like these.
