The difference I see with Texas is Barnes wasn't someone capable of building something elite and yet they still had success.
Shaka can build something elite.
Can Mack or Miller?
They weren't much before Barnes (some success under Penders, but i think 1 Elite Eight was their best run), and Barnes ddi take them to a Final Four. Obviously not the same success Donovan had at Florida though.
My jury's still out on Texas, but Shaka was an excellent choice.
Despite all of Billy the Kid's success, is Florida looked at as an "elite" Basketball job? I say no.
