It sounds like he's persona non grata at Big XII schools, or maybe all NCAA schools. AFAIK, he didn't do anything to OU in particular, so that's the only reason I could think of for his presence to be such a lightning rod that they'd address it with Lebby before he was even hired.Briles is trash, but his son in law is Lebby, his grandkids were there. He was on the field after the game as all the families were. He wasn't on the sidelines or there in any official capacity.
