Izzo didn't turn the program around- he improved it. But Heathcote had won a national championship and had been to 5 of the previous 6 NCAA tournaments.
Virginia- Bennett has been amazing but that program has a higher floor because of the talent base in the region.
Prior to Bennett they had been to the tournament half the time since 1980.
UNLV was all Tark but we know he cheated big time.
It is really, really tough to turn a program around that has been mediocre for 40 years. The best turnaround jobs I have seen of such a program is obviously the combination of Bennett and Ryan and of course Coach K and Duke. Unless you want to count Dan Monson and Gonzaga....

Even with Duke, Bill Foster prior to Coach K had been to three straight NCAAs...
Minnesota? We have been to the NCAAs 11 times in our history and 4 were vacated. The job can be done here- but it is tough. As I write this post and consider the history of other programs, I think that either sticking with Pitino or perhaps going to Fred Hoiberg might be the way to go. I don't think we can get Musselman. Perhaps Hoiberg would be the shot in the arm for 6-7 years that gets the program going and he brings up a great assistant that can take it over? I have previously said I think Hoiberg is too short term of a fix but maybe that scenario would work. I thought that would work with Tubby, but obviously it didn't. Tubby had weak assistant coaches for whatever reason.
