Very solid effort. Won't have the real answer until Game 1. I would only make a few tweaks, as I see things at this time:
3rd QB = more likely Huard, with Davis to PS for a year of learning.
4th OT = more likely Bender at LT, with Boone or Howard to PS.
6th WR = none, only 5 WR in the Raye offense, Battle could well "retire".
5th CB = Hudson stays by using Battle's roster spot
back-up OLB = M. Harris plus a veteran player not yet on the roster, Long to PS.
back-up SS = Reggie Smith beats out Jimmy Williams. Williams cut.
back-up FS - Lewis Baker beats out Curtis Taylor, Taylor to PS
