Let's be realist here.............
It's going to be, barring injury...........
Foster
Jones
Brown
Beasley
w/Roberts as the return man
Those are locks, unless their are personnel developments at the WR position.
The battle is for the 6th spot, with a host of possibilities.
Duke Williams is the favorite because of his size, ball skills and being a red zone threat.
It should be an interesting battle.
P.S.,
If the Bills fail to add a DE (or feel set there)...........................
They might explore a big name WR again, so the name Jones will still be a lock for one of those top 4 spots, but replace the first name of Zay with Julio (as Zay would be included in that trade).
Beane did heavily explore AB and OBJ, so I don't think exploring another big name WR isn't out of the question for the next 3 boring football months.
