This kid should gut it out and just go to USC in the summer/fall. If he redshirts, Kiffin will prob be gone this time next year anyway. Much better choice than ending your football career aspirations by choosing to go Washington at least.
I think the article said Notre Dame was in the mix, which is far more legit for a D lineman who is top 10 at his position. I'm sure at least a dozen other AQ schools would take him.
The kid already put in the work to graduate early, presumably so he can participate this spring and compete for playing time this season. Why wait if be doesn't have to?
