As I have said on other Boards, Buzz Williams would be an absolute home run hire. He is #1B on my list (with pipe dream Bruce Pearl being #1A) and everyone else a distant second. The question is not whether Iowa would consider Williams; it is whether Williams would consider Iowa.
I live in Wisconsin and two years ago I chided my Marquette friends for hiring a "no name" coach to succeed Tom Crean. That was until I met him in person at a Marquette fundraising event. He was the best public speaker I have seen (and I have seen many) and he completely captivated the room. It was clear then before he even coached his first game at Marquette that he would be successful.
1. Williams has an extremely charismatic and energetic personality that would sell the program in a way similar to what another Texas was able to do for the football pram 30 years ago.
2. Williams is a proven recruiter at the Top BB conference in the country. He has a Top 5 recruiting class and recruited Wisconsin's top basketball player (a Madison native) away from Bo Ryan.
3. Williams has made two NCAA tournaments from the Big East. Ironically, Marquette is scheduled to play New Mexico in the 2nd round, barring upsets.
The question is not whether Williams would be considered by Iowa, but whether he would leave a program where he as strong loyalties to for taking a chance on him two years ago, a school that has average attendance > 16,000 and the strong support of the administration and fans to take on the massive rebuilding project that is Iowa.
I believe their is a less than 50% chance Williams would consider Iowa but he is a visionary and if Barta can convince him that the support will be there and that Iowa offers the platform of being a member of an expanded Big Ten that offers national exposure (including Texas, where Williams is from; four Texans are on MU's roster) vs. the Big East which may be imploding, I could see Iowa having a chance.
