I think Sean Miller is vastly overrated by this board because he's perceived as being part of the Pittsburgh tribe, when he has shown absolutely no interest in, loyalty to, or affection for the city. Were he from Chattanooga, TN, he'd be largely ignored or roundly criticized.
He's geographically from here, but there is no reason for his abilities to be overstated when -- really -- he's done pretty well in some extremely advantageous coaching positions. Arizona and Xavier are programs that were successful before him, and will be (or currently are) successful after him. They're outstanding programs that he's had little to do in establishing.
Xavier has made 24 of the last 28 NCAA Tournaments and went to an Elite Eight the year before he took over, and he was gifted Jordan Crawford as a questionable academic transfer. He did well, but he didn't take a program out of nowhere and make them relevant. Heck, he really didn't even bring them to a better place.
Reading this board, Matta going to an Elite Eight the year before Miller took over should've springboarded Sean to heights never before seen with the Musketeers. Elite Eights are super relevant and March is all that matters, after all.
He is, at best, a wash with Dixon. I have little faith in his ability to recruit at an Arizona level at Pitt -- Xavier has shown he's not a Lavin-type -- and his offense is sloppier and more disjointed than anything Pitt runs. If people are going to pine for an upgrade, then don't point to Miller as an example of one. The fascination with him is one borne of his birthplace being Western Pennsylvania --- nothing more, nothing less. It's amazing how much weight that carries in this region relative to the rest of the country.
