If you look at the 105 man roster, it just seems odd to me. Obviously the coaches have seen the players but we're eight deep at RB, have 12 WRs, have a walk-on fifth-string QB, and have several walk-on players on defense who are well down the depth chart. I'm sure a bunch of those guys are going to be on special teams and you need those guys in camp but we have at least one freshman walk-on. How can they know he's going to be more of a contributor? We even have a walkon offensive lineman on the roster who's never played in a game and can't be higher than fourth string. Plus he's a guard and we're deeper there.
I just think the only reason for leaving one guy off is to send a message that he's not wanted and basically try to run him off. I just think it's an odd choice.
