He's a good recruiter and a very good defensive coach. He has a very consistent defensive profile and his defenses are always good. To me that shows that he has a plan. His defenses deny 3PA and smother teams on the perimeter, and have athletes inside to contest at the rim. Basically, they allow a lot of midrange shots, which percentage wise are the worst shots in basketball. It's a very statistically sound game plan, and it's worked for Hurley in defensive sets of all sizes. Hurley could definitely stand to improve his offensive approach. What's funny is that the Hurley brothers each excel on opposite ends of the game.
Not sure what options there are out there that are better coaches. Musselman may have him beat, but Hurley's east coast connections make him a better fit IMO.
Crean in my opinion is a non starter. He's basically the face of "good, but not good enough" and he is a meme of a person who manages to look stupid 24/7. Even if the latter doesn't really matter for basketball, it's uncanny. If all goes horribly, then sure, consider him. But I don't envision it getting to that point. Mark Titus is the man, but he has no connections to the program and basically has no insight to give in regards to the next UConn hire.
