Toney, Matos, and Simmons all have the potential to be break out players but I doubt that all of them will have an opportunity. Miller and Brown (if healthy will start). That leaves Buchholz, Toney, Simmons, and Matos fighting for second team snaps. If everybody stays healthy two of those guys are going to struggle to see much time.
TOS predicted Holland at TE and said that Bowers might be passed by one of the freshman if he's not healthy. These two kids are juniors so something tells me that one of them might move on if they can't get meaningful PT (even if due to injury). I'm rooting for Bowers.
WR seems to be Johnson and Thompkins in the slot. Someone between Polk, Hamler, Hippenhammer, and Shorter will have to make an impact. I also think we see more of Stevens as a 4th WR, replacing either Holland or Bowers when we go w/o a true TE.
Roy mentioned Reid and Menet. I think Reid was already a dominant player two years ago so it's only a matter of how he comes back to form after his injury. Menet will probbly start along with Fries, Gonzo, McGovern, and Bates. Wright will also be in the mix. Maybe Miranda. Jenkins is a junior so it's pretty much now or never given that Wright is the only senior.
