Miller expected to make a decision by the end of the weekend according to ESPN. I suspect he decides to remain at AZ.
I can only imagine the meltdown at Arizona if Miller goes, but I'm guessing the Wildcats will be fine with the program's prominence.
EDIT: Miller stays at Arizona...http://sports.espn.go.com/ncb/news/story?id=6504485
My money is on Mike Brey. Jay Wright and Jamie Dixon are in jobs that are just as good as Maryland or better. Shaka Smart might be another possibility.
While I think Tubby would have gone to Maryland after Kentucky had the job been open then, I've always felt he was going to retire at Minnesota and try to hand the job to Saul when he's done.
Maryland does not need to be rebuilt.
