As I recall, they had a falling out on Team Texas before either one committed...WW ended up signing with us.
This is my point, the failures now have to do with what happened after the Elite Eight...it's not WW's fault. Don't know how closely you followed his recruitment and freshman season, but everyone that I confered with indicated he would be at OU a max of two years (unless he was injured). People were afraid he would bolt after his freshman season (he was a projected lotto pick, in the 12-13 range I think). Capel failed to take that momentum and turn it into continuing success, that's on him and the corresponding players he recruited.
The Elite Eight run put a buzz around our program, we just didn't cash in on it. We had a Final Four team that year when healthy, if we steal a #1 seed there is a solid chance we are playing the first weekend in April. If that is a possiblity, you have to go for broke. You play to win championships, and those opportunities don't come around very often. I just don't see any alternative.
