It's going to be said often, but this is a solid hire. Not an obvious home run, but not a stretch by any means. Crean is 42 years old and has a Final Four on his resume and eight years as a head coach (about a .650 winning percentage at Marquette). The biggest knocks: a hot temper (come on, we've seen worse) and a less-than-stellar NCAA Tournament record absent Dwayne Wade. Still, IU hired a successful coach from another power conference program despite NCAA issues hanging over the program. It could have been worse.
Here's a link to Crean's Marquette bio.
He's been subject to quite a bit of well-deserved criticism, but once again, Rick Greenspan managed to hire a coach without much media coverage of the process (although certainly the Bennett pursuit was an exception).
