Well Miller is an east coast guy and UConn is a better job than Arizona despite what you think. uconngb, you really don't think any big time coaches would be interested in the UConn job.
I love UConn and yes the "east coast guy" aspect could play a role but I wouldn't bet my house on it. Maryland is a decent job also and they have the whole Under Armour thing going for them also and they couldn't reel him in.
As for UConn being a better job than Arizona. That is a matter of opinion. Of course I'm a UConn fan and want it to be tue but a large part of the UConn job is Calhoun. Currently, (and I know they are going to be updated in the next few years, hopefully) Arizona has a better training facility, a pretty darn good history (following another coaching legend in Lute Olson), has some distinguished alums in the NBA, and is close to both Vegas and LA (recruiting). Not to mention he has probably the top class in the nation coming in next year. It may not be much better than UConn but the facilities probably put it ahead right now in terms of jobs. At best it's a lateral move (unless location is that big a deal or UConn can throw more money at him). ATM he is paid slightly less than Calhoun.
