Prediction: Provitt will end up on a college football roster (most likely in Florida) within 12 months.
If i had to guess, I'd guess the reason for his decision may be that he's had a concussion or two, and decided he didn't want to risk more. I respect his decision, and would be surprised to see him playing football elsewhere. I think baseball is a more likely bet.
I followed langston on Twitter for a while after he signed and I can tell you that based on those tweets, he had a serious GF down there. I gave up following him, because I could care less, as they say, about his love life, but I figure that that had a little to do with his decision. Just guessing.
