I think I can come up with scenarios where as many as 12 redshirt, but it's highly unlikely. We'd need some guys who aren't known as producers to produce, and some guys who aren't known for their durability to be durable.
The obvious RS candidates are Hager, Omenihu, Houston, Townsend, Locksley and Major, so I'll ignore those.
RB: We played with three last year and were fine. Warren and Foreman are probably competing for reps. If Catalon can stay healthy (

), we redshirt Johnson.
WR: I think Newsome redshirts. There's too much competition for those reps, especially if Hot Rod's knee is good to go.
OL: I don't see any way Williams (duh), Vahe or Hodges don't make it onto the field. Nickelson and Thomas are likely redshirts IMO.
DL: Covered 'em. Vasser plays.
LB: The coaches will RS at least one of Wheeler and Cherry.
DB: Davis is the only one I think has a better than 50% chance of redshirting. I think Hill and Elliott play early and often. The question here for Elliott is whether Colbert gets his shit together. With his versatility, can Locke find his way onto the field? My guess would be special teams and maybe backing up Bonney. And as crazy as it sounds with all the positive reports this summer, I could imagine Boyd redshirting. I know he's a tremendous athlete. I have questions about his physicality and technique.
