In no particular order:
Billy Clyde wouldn't be half bad, but that he didn't have success at UK concerns me.
Josh Pastner, OU is still a better job than Memphis and the kid can recruit like the dickens.
My personal choice would be taking a long hard look at Terry Evans. He is proving that he can get it done at a lower level, could wrap up Oklahoma kids and maybe bring in a guy like Jeff Webster to work the North Texas kids. High risk, but high reward potential there, but if you could put that staff together and possibly bring in a guy like Steve Eck to be an assistant, you'd absolutely be able to recruit well in areas where OU typically gets players. I look at the joke we all thought Frank Martin would be...who is laughing now?
BUT, the likely scenario is that Capel gets another year, becuase otherwise Boren and Castiglione would have to admit they made a mistake and powerful dudes like that do not like to make that admission.
FWIW, I think I made a mistake too. I really like Jeff and I thought that last year was an anomoly based on kids that put themselves first, but you just can't lose to Chaminade when you are at OU. Just can't.
