1. Sean Miller (if possible, hands down option #1)
2. Kevin Ollie (with Hobbs and Miller on staff and very well paid) recruiting will be great, half the battle
3. Brad Stevens (Can't deny the success , replace with Shaka if Shaka hadn't gone to Illinois)
4. Karl Hobbs (I think he will be a very successful head coach again)
5. Billy Donovan (Gainesville loves him but New England never leaves the soul, you never know)
I don't see why Miller would leave Zona. He's building something up at one of the traditionally good elite programs. Is he an east coast guy? Why do folks bring him up? I'm not been super impressed with his Xs & Os. I tend to like a coach that stresses hard nose D. That doesn't sound like Zona or Miller.
I don't know what to think of KO. I sure would have liked to see what he could have done this season when JC sat out a couple times. It was an obvious window to do that and IMO could have been handled with George playing the role of mentor, with the understanding that KO is a possible candidate to succeed JC. Ideally, you want a coach that has a track record of winning and bringing in big time recruits. Ollie might turn out to be an outstanding head coach, but we won't know till he gets that job here or somewhere else.
Stevens has proven he's a successful coach. I have no problem with his system. His teams run a variety of stuff on offense and play some pretty tough man-D similar to what UConn runs. Since he recruits at a different tier for the most part, he would have some proving to do as far as bringing in blue chip talent. He seems to have a good nose for talent though. His players seem to perform higher than their rankings dictate. I think his overall success and name he made for himself would attract high level recruits if he coached at a high major program. He'd be my top choice but I've heard he's a mid-western guy who might not want to come east.
Hobbs - His resume in both winning and recruiting is lacking. Nah.
Donovan - Now he's an interesting one. He's been at UF for a while. I wonder if he'd like a change in scenery. I haven't watched his coaching style all that closely. He seems to do well when he has a super athletic line-up. Just not sure how well he is able to adjust his coaching to his personnel. He's recruited well, but hasn't always won the recruiting wars against the big boys as much as I'm sure he'd like. You often win an NC not with those 1 or 2 big time recruits but with the players who round out that 8 to 9 player rotation.
Some have mentioned Shaka Smart. I'm not sure what I think about him. He seems to get his players to play awfully hard. He sometimes plays that full court pressure D, reminiscent of UConn in the early 90s. The problem with that is teams that play that way usually run out of gas and simply can't win an NC playing that way for 6 games in a row. But for those who think that's all he has his players do, that's not true. He does get his players to play tough half-court D. It's his offense that doesn't seem the most imaginative. I'm not sure what to make of that. Recruiting, he seems to have a nose for talent. Until he arrives at a high major, it's hard to tell how good he'll be at recruiting blue chip talent.
One thing we have to keep in mind is that the best coaches, although they have their preferred styles, learn how to adapt to their personnel. Some successful mid-major coaches do a great job at the next level and adjust their offense and defense to the upgraded talent. Some don't. Until you give them a try, who knows? What I look for is how they handle the players they have, handle themselves along the side lines, how they manage games (close, from behind and with a lead) and from a selfish standpoint, run a system that I enjoy watching. I like a team that turns teams over, is good in transition but is solid in the half-court, where NCAA championships are often won.
If I had a choice, I'd be okay with Stevens, Smart and Donovan. If they give it to Ollie, I'd be fine with that too. It's just we won't know what he brings to the table until you give him that shot.
