I agree with them in most areas.
QB: I think I'd go with 2 QBs, which would open an extra roster spot else where.
WR: I'm not quite sure why they would go with Myles White unless he's standing above the rest which I haven't heard about. It's be a tough choice between high potential but mistake prone Chris Harper, the STers/physical Kevin Dorsey and Jeff Janis who might have the best long term potential.
DL: Unless Guion is ready to play very soon I'd just go ahead and put him on the PUP list and tell him to be ready by mid-season and keep Pennel going/learning.
OLB: I haven't really seen Carl Bradford flash much, but he's a 4th round rookie and they normally try to keep their rookies. Though the Packers have cut a 4th round rookie before (WR Cory Rodgers). But they'll probably try to keep him on there.
DB: CB Rolle has been making plays, it might be a interesting battle between Rolle and STer Banjo for a DB spot... normally they only keep 4 Safety (and 6 CBs) but with Hyde being able to play CB/nickel/dime role they might be willing to keep 5 of each.
Extra spot: Created by going with only 2 QBs... I'd look at keeping one of the following with it, RB Neal, WR Harper, WR Dorsey, WR Janis, CB Rolle and S Banjo
