Willie was a little low on the depth chart, (low 2nd string, high 3rd string type), but his family moving out to LA also played a large role in transferring to UCLA. It was a very friendly departure, which isn't surprising because Willie always had a big smile on his face when I saw him.
OSU had a lot of depth at DE, both current and incoming, much more than he'll see at UCLA:
Starters/regulars:
Jr Gibson (probably drafted next spring)
Jr Heyward (returning starter)
Jr Worthington (DT, but plays 3-4 DE a lot too)
So Williams (stud)
Other DEs:
Sr Wilson (former starter, lost for yr two straight seasons)
So Thomas (LB/DE type hybrid, finally coming into his own)
So Wells (stolen from SEC country vs UGA, etc)
Fr Newsome (LB/DE hybrid, will redshirt, good pass rusher).
Fr Fellows (5* SDE type)
DT depth chart (Mobley was looked at as a possible combo DE/DT guy):
two seniors & junior in top-3
two stud frosh in Goebel/Simon, plus a solid 3rd in Bellamy
Incoming recruits:
2010 LB/DE Jamel Turner - all-american as a junior, academic/off-field trouble, but a phenomenal talent
2011 DE Steve Miller - 5* type prospect, probable future buckeye.
2010 Darryl Baldwin, JT Moore - both developmental guys, but very early targets by OSU
2010 LB/DE Durham - sleeper out of texas, could put his hand in the dirt
