Not to keep beating a dead horse here, but I see Colon as the perfect backup, can play tackle or guard. Peterman is just a jag brought in for depth. Oboushi is a RT, and Campbell is a project who should be on the practice squad. Schlauderauff is a nice backup because he can play center also, our new Rob Turner for a few seasons. Winters is a future starter and his future is now. That leaves Vlad as the starter in my eyes.
I think they'd like Vlad to win the job and will give him the opportunity to do so, but I also think they have a serious lack of faith in him, which is why they were sure to bring in plenty of competition and have numerous backup plans. Vlad will get his shot throughout camp, but don't be shocked if he ends up riding the bench or even getting sent packing in the final cut downs. He wasn't able to beat out a 6th round pick for the last 3 years, so I wouldn't bet on his ability to beat out all of the guys he currently has up against him at his position, most of whom were hand-picked by the new GM, which he was not.
