Not a joke:
The tweets are secondary infractions - probably no penalty. Next Jim O'Fallon's NCAA Infractions Committee will go after schools for giving their players textbooks. Oh, wait - he's already done that. What a silly thing for a former Harvard Law fellow, noted first amendment scholar, and self-styled Frank Nash Professor of Law, Emeritus to spend his time on. But it does distract people from the NCAA's real corruption - and presumably he has no trouble getting someone to pay for his Fiesta Bowl tickets.
