Chamberlain Oguchi is also apparently transferring. Here's Bob Rickert's blog item and the Oregon press release. Rickert notes that the Ducks have offered a scholarship to Brad Garrett, a 6'5" JC shooting guard to replace Oguchi.
This is really too bad. I always liked Champ, and was hoping he'd be able to put together a strong senior campaign after suffering through a tough junior year. Hopefully, things work out for him.
