Call me crazy, but Frank Martin.
First, he's legit good:
2007-2008: 21-12 (10-6)
2008-2009: 22-12 (9-7)
2009-2010: 29-8 (11-5)
2010-2011: 23-11 (10-6)
Each season they went to the post season and each season they won at least one game, including making the Elite 8 in 2009. He's 8-8 in post season play. The Big 12 has been a tough conference the last couple of years too. Outside of that first year, he hasn't really been working with a ton of talent either. Once Bill Walker and Michael Beasley left after their first year, they have one five star that contributed minimally and transferred after a year.
Second, he seems to be doing it the right way. Under his leadership KSU has a very good graduation rate and has improved their APR significantly. What works against him is the fact he worked for Huggins, was originally hired to keep Beasley and Walker, and ran across a bit of a scandal while coaching high school in Miami. He seems to be pretty clean regardless. His chief recruiter was just hired by Maryland, and I think Mark Turgeon is a stand-up guy who wouldn't hire someone that operated in the gray. He also looks certifiably crazy, but, hell, I'd get over that.
Third, in Kansas he has a less extreme version of the Carolina problem, but still achieves consistently excellent results.
Fourth, he's attainable. He makes $1.6mm right now, but given he's stuck in Manhattan Kansas I imagine it wouldn't take as much as you might think to pry him away.
Fifth, this has all been a total waste of time because Ron Wellman would never hire Frank Martin. Never.
