I think coaching in the NBA made Kelvin Sampson a better offensive coach. I'm often wrong, but I don't see Houston getting seriously tested until the Elite Eight. Also, unlike at OU when Kelvin struggled mightily in toss-up games (1-6 when seed separation was three or less), I think he will win most of them now.
I know you are just taking a dig, but Houston has a #2 seed and probably has 3 bigs better than any OU big not named Manek. I think their recruiting has been fine.
