In response to Army2LT's comment:
I find it remarkable how much it changes in just a few months. Guys who were seen as top ten picks fall to the 2nd round, and players come from out of left field to replace them. I remember watching Floyd in the bowl game and wondered why no one was talking about him, and now he's jumped into the top 5 in many mocks.
I love going to this site to watch the risers and fallers.

Check out the recent fallers-
Star Lotuelei -10
Keenen Allen -7
Damontre Moore -17
Kevin Minter -7
Jonathan Hankins -10
These players could be ripe for the pickin' at #29 (or maybe a short trade up).
Star was understandable, given the report of his heart problem. Even if some doctors say it should not be a problem, teams will wonder how hard they can push him or allow him to push himself.
Hankins, Allen and Minter may be just a matter of fit (positional need and scheme) with whomever is picking.
Moore I think is the only real faller there.
