It's a pretty terrible year for Warren to be declaring, as the Sooners put on quite a fail this season. They lost Blake and Taylor Griffin to the NBA, and Austin Johnson due to graduation, yet they scored two big name recruits in All-Americans Tiny Gallon (already drafted) and Tommy Mason-Griffin (who was never going to be. Hey Tommy; if Willie Warren can barely get drafted, you had no chance.)
