Beard 1) doesn't need further evaluation and 2) likely has no interest in IU, IMO. Oats? Who knows at this point. And I don't see a scenario where Dolson can wait beyond next spring (season 5)--either Miller salvages something out of this season and/or makes some real, tangible progress in 2021-22, or the issue becomes unavoidable.
I've always felt that the likelihood of Brad S returning to college basketball was greater than most people assumed. Sure, he didn't like college recruiting, but MOST COACHES DON"T EITHER and at some point he may think he's taken the Celtics as far as he can, even with all those "awesome" draft picks Ainge accumulated.
Brad has to know that if he returned to college BB he wouldn't have to work nearly as hard recruiting kids as he did at Butler--he would just have to pick the right school and rely on his reputation/image as Butler's F4 coach and the Celtics coach. Which makes me still wonder whether he might ultimately end up at, yes, Duke or maybe UNC. But not, unfortunately, at Indiana.
