A popular line from the pro-Crean camp when this argument came up last year was that Stevens wouldn't succeed here because he isn't "flashy" enough. They then proceeded to dismiss his Horizon League success because the teams he had there would have lost a lot more games if they had played in the Big Ten. Some of them even went as far as saying that if Crean went elsewhere, he'd turn that program into a powerhouse and we'd instantly regret it.
If I had to make a gun-to-head prediction, I doubt Stevens ever comes here. Things would really have to turn sour in Boston for him to leave that behind. They have a bunch of first-round picks (thanks to the stupidity of the Brooklyn Nets) and all he has to do there is coach. I'm not an insider by any means, but I remember hearing that a big reason he left Butler when he did was because he wasn't happy about their move to a bigger conference, since it meant he would have to recruit against high major coaches and he wanted no part of that because of all the cheating that goes on. I don't think it would be difficult for him to recruit here at all (Crean has made it 100 times harder than it needs to be due to his personality and lack of results), but I think that would be the major reason he would ultimately turn the job down if offered.
Now…having said all that, I really hope we didn't bring Crean back to waste this season because we thought there was a chance we might get Stevens next spring. There are other good coaches out there who would gladly take this job and accomplish so much more. Hopefully we find one in a few months and finally cut our losses.
