why are people assuming that ou did something wrong? they don't benefit from gallon accepting money from an agent. and they certainly wouldn't be funneling money through one (no one is that Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!). "hey tiny, i see you daily and can slip you untraceable cash at any time, but instead i'm going to have some random agent who openly tweets about flying to norman to talk with college athletes wire some money to your account, 'kay? 'kay.").
what obviously happened is that gallon took some money from the dude, and when the asst coach (or the whole staff) somehow found out about it, they tried to manage the situ privately rather than immediately report it. bfd.
and ou would have fired capel this year if they were going to fire him. he has at least 2 more years, and will judged on on the court success.
