It would seem to me they wouldn't allow this based on whats out there.
...unless there is more to this. Only thing I can think of is...So maybe Carlisle saw something improper at SC, and, in light of the culture and current sanctions, felt he could not be part of it. In that case if he were a whistle blower of sorts...NCAA would be looking at a nasty precedent if they DIDN'T let him transfer and play.
Not at all saying thats what is going on...just thinking out loud trying to understand why they think he has a chance to do this...
