My thoughts on those mentioned ...
I don't know his level of interest, but Chris Mack has been almost off the charts good at Xavier, including taking us down twice in the last two years. He would be my first choice.
Archie Miller would be my number two, evaluating his own performance as a HC rather than his brother's.
Neither of these guys would be the home run that Marshall would have been, but to continue the baseball analogy, they would be extra base hits.
Prohm is not at the same success level as these guys, but he is a promising youngster. As I told TP whenn he texted about Prohm, it does bother me a little that some 17-18 years ago we hired a young, promising HC from Murray State. That guy started well, took the program further in the big dance than it had ever been, got a huge contract, and proceeded to go into decline both with regard to coaching success and in his personal life. Still, Prohm and XCMG are two entirely different guys. There would be a distinct lack of enthusiasm in the fan base, and the U of A would owe it to Prohm, as well as to these fans, to promote the heck out of basketball.
I would not even consider the younger Pitino until we had firm negatives from these guys, and it might be the time to look at someone once considered a hotshot but now off the A-list, such as Jamie Dixon, rather than slipping down to mediocrities.
One thing is for sure. The program is in better shape today than when we dumped Hobbs, as well as when we dumped Gottfired.
