Arguably the top junior college prospect on the board for Texas is Contra Costa CC's Desmond Harrison, an offensive tackle the staff believes can come in and compete for immediate playing time.

Believed to be down to Texas, Oklahoma, Arizona St., and USC, it appears that one of those schools is now out of play for Harrison:

Seems like USC has pulled off of juco offensive linemen Desmond Harrison. Good news for Arizona State, Oklahoma and Texas.

USC had to dump yet another player on Tuesday, informing four-star defensive tackle Kylie Fitts that he would not be able to enroll early, though there are four overall spots left, just none for players who want to be on campus for the spring semester.

So Campbell probably was not an attrition candidate, but it's more likely that USC decided that they didn't need another offensive tackle with one committed already and youth at the tackle position.

Looks like this one may come down to a good old Red River battle.
