I am pretty sure that whole "it was not drugs" thing is BS. He had just gotten back from Bonnaroo. For anyone who is not familiar, it is Woodstock-esque. His teammates said he had been really stressed and many "mind altering" drugs are readily available there. Of course, it is possible it was not drugs but I find it hard to believe he would flip out like that with out them. He gets good grades, etc. I think it is just a case of a typical college student with atypical pressure on him that went a little too far to relieve his stress and accidently took it public when he was at a loss of his faculties.
I also do not feel it puts us in too bad of a position. It is scary to think about starting a QB vs Miami that has never played in a college game before. But he has a lot of experience surrounding him and Miami last a lot of players. Plus it is in front of a (usually) friendly crowd on a familiar field. Then after that he has a powerpuff game vs the Citadel. But who knows?
