If he can play somebody will give him a chance.
It is going to be very hard for him though. He is probably going to have to go to a Juco and first order of business will be to prove himself to his teammates, especially those who are African-American. There is no way he slides in unnoticed, this thing has already drawn far too much attention for that to happen. He acceptance will not be instant, he isn't going to fix this with a statement, he will have to show his new teammates on a 24/7 basis with zero room for error.
If the succeeds with that then his next step would be back to the BCS level but even if he does very well on the field at the Juco it will be with a bottom feeder P5 program or a G5 program willing to risk him for the talent.
He is not only dealing with the racist stuff.
He aired dirty laundry in public of his former school and he also posted a video (same one with the racist stuff) with closed practice footage on a public network.
