Ex-Sooner-for-a-week Brandon Keith is quoted on The Arizona Republic calling OU "dirty." Keith references some ambiguous shenanigans going on with the OU program around the time of his departure. Maybe he's referring to the Bomar-Quinn scandal? Otherwise, I'm sure the NCAA would love to know what he's talking about.
Based on this article, it sounds like Keith has had some bad luck in recent years. First, he couldn't work out because of transcript problems. That must have really been a really tough pill for a 335-pound dude to swallow. I can understand why that kind of frustration would cause him to lash out at the strength coach. Then, he gets Tased by an overzealous cop for being in the wrong place at the wrong time: an apartment complex brawl.
