Marshall might be a more difficult personality, but of the 2, Marshall is the better coach. Marshall already has a hard on for beating KU. He's the natural choice. And fwiw, the pecking order still is Marshall, Shaka and then Miller. I think Tejas only hires Shaka over him if he's willing to take the job for significantly less $$. And I don't think that'll be the case.
Shaka then stays at VCU, because I really don't see him wanting to replace 1 of his mentors at a school that really doesn't value hoops, despite the amount of $$ they might throw at you. I'm guessing Miller stays away from Bama too, and they end up with White. GT would have been the job for Miller, but GT has its collective head up its collective ass. Then Shaka ends up at UNC in a year or 2 when Royboy retires because they just don't have a family candidate worthy of the position, and they realize that this time around after their Doh! moment.
