I get the impression that these are the roster battles:

RB (1 spot available and only keep 4 this year) Herron vs. Leonard vs. Peerman. My guess is Peerman makes the cut.

TE (1 spot available) Charles vs. Cochart. My guess is Charles makes the cut.

WR (2 spots available) Binns v. Whalen vs. Hawkins vs. Tate. My guess is Binns and Hawkins make the cut.

OL (2 spots available) Bell v. Boling v. Hudson. My guess is Bell and Boling make the cut.

DL (1 spot available and keep 10 this year) Sims vs. Harvey. My guess is Sims makes the cut.

LB (1 spot available) Rey vs. Burfict. My guess is Burfict makes the cut.

Secondary (2 spots available) Miles vs. Iloka vs. Sands. My guess is Sands and Iloka make the cut (as does Newman).
