If anything, I'm surprised they expelled him. After all, Dana Altman recruited a known (alleged) rapist who transferred to Oregon only to be accused of raping someone again (allegedly). That's in addition to the gang rape allegations involving Brandon Austin, Damyean Dotson and Dominic Artis who all kept playing.
And someone should ask Kayvon Thibodeaux about how much money he's getting at Oregon. It was long rumored before he even made a commitment that he was holding out for the highest bidder and that he wasn't exactly shy about it.
