Harris has been committed to Alabama for almost a year now, but most insiders do not believe that he will stick. He did a recent video interview after his Junior season, in which he doesn't seem too enthusiastic about his Bama commitment.

In another recent interview he did, he states that; Michigan, Ohio State, Cal, USC, UCLA and Washington have been coming after him the hardest, but Ohio State is the only school that he knows he's going to visit for sure.
"Michigan, Ohio State, of course Cal and USC, UCLA, Washington's been coming -- pretty much everybody," Harris said after he and TMP Elite won the Kenion Training 7on7 Kickoff on Sunday. "Alabama, of course, they come. I'm visiting Ohio State pretty soon. That's it so far. That's one place I do want to visit, the most. That's the only one I know for sure I'm going to. I don't know the rest."
