anyone know the name of...

the black man in the coaching scrubs on the U of Oklahoma sidelines? He's an ex-player, for whom I can't remember, wears one of those circle beards, built like a db or rb. I have searched their listed coaches and he isn't on that roster. I know the face but can't put a name to it.

Its bugging the shite out of me and that is all.

thanks in advance.
