What players have exceeded/fallen short of your expectations?

This board is boring today.  Maybe we can have a discussion about this.

What player(s) has exceeded your expectations in your time as a Michigan fan?  Conversely, which player(s) has fallen short of your expectations?  I'm not looking for anyone to bash any players, but I'm just curious to know - who were you really wrong about?

EXCEEDED: I was not a big fan of Ryan Van Bergen when he came out of high school.  I thought he was a Pat Massey clone.  I figured he would bulk up to play defensive tackle but he would get pushed around.  But he had a good season last year and now I expect him to have a good season replacing Brandon Graham at DE in 2010.

FELL SHORT: I really thought Marcus Witherspoon was going to be a great linebacker at U of M.  He was fast and aggressive and I was extremely excited about him when he signed in 2008.  He had a problem with admissions, which has nothing to do with his football ability.  But then he ended up at Rutgers, couldn't get any playing time, and is no longer with their program.  I don't know if he's transferred to an FCS school or what exactly he's doing now, but I guess I was wrong about him.  Hopefully he gets his head on straight, whether he continues his football career or not.
