With Michigan's relative youth on the depth chart there are sure to be several players from the 2010 class that will make a contribution this year.
However I think that true-freshman starters are something you don't really want to happen.
Let's look at who started as true freshman (at some point) in 2009:
Quarterback: Tate Forcier
Running Back: Vincent Smith
Linebacker: Craig "Death" Roh
Box Safety: Jordan Kovacs
This is way too many freshman starters, especially since V.Smith was the only player to actually beat out possibly better options.
2010 should see a lot less true freshman from playing. I think that Troy Woolfolk will be the Deep Safety so one of the CB spots will be open if JT Floyd doesn't win the job. Also the Spinner position will be open.
2010 Potential Starters
Spinner: Josh Furman/Marvin Robinson
Cornerback: Cullen Christian/Demar Dorsey
Punter: Will Hagerup
Hagerup is almost guaranteed to start but the other 2 positions are undecided. It is quite possible Michigan will have no true-freshman starts in 2010. Yay depth!
