I don't think enough attention is given to Greg Marshall. He is an Elite coach. His Winthrop teams nearly pulled off some historic upsets against top seeds in the Tournament. Moving up a level, to Witchita State, he has elevated his success further. He has made the final 4 as a 9 seed and the sweet 16 as a 7. His "down" years still include tournament appearances and conference titles. Given IUs resources, i think he would replicate his success in the BIG 10. He would be a home run hire.
Tier 1: Stevens, Donovan
Tier 2: Marshall, Bennett
Tier 3: Miller, Collins, Few, White
Tier 4: Disappointments
We shouldn't settle for anyone outside of the first 3 tiers imo. I think they would all be successful at IU. If we could get anyone in the first 2 tiers, it would be a home run. We would be viewed as elite again. Stevens and Donovan are both unlikely, but Marshall or Bennett would consistently compete for BIG titles and high seeds in the Tournament. We would have a shot every year. We would be the premier program in the BIG 10 again. I think that's what everyone wants.
