The Bills have Stevie Johnson as their No. 1 wide receiver, but who lines up alongside him remains to be seen.

David Nelson seems like a likely option, while third-round pick T.J. Graham should stick around in Buffalo for a while. After that, the depth chart remains unknown.

"You want to see guys go out and perform in the games," quarterback Ryan Fitzpatrick said. "Unfortunately, I don't think the receivers had many opportunities in terms of being able to catch the ball or run after the catch."

Marcus Easley, Kamar Aiken and Derek Session are fighting for time. Donald Jones, Naaman Roosevelt, Derek Hagan, Ruvell Martin and David Clowney are also on the roster.
