IMO, if IU had truly been his dream job, he would have left Michigan after one season, just like DeVries left West Virginia.
Goodman is an idiot, but in this case I think he's probably right. Dusty never seriously wanted the IU job because (1) he didn't want to coach in a fishbowl environment, and (2) he was concerned about how a potential failure at IU could affect family members who still live in Indiana. Those are reasonable concerns.
That said, circumstances have changed dramatically. He just won a national championship and is now headed to the NBA. Concerns about the IU fishbowl or the possibility of failing there are likely much less significant than they were a year ago.
If both DeVries and Dusty struggle over the next few years, and college basketball reaches a more stable place with NIL and roster management, I could easily see the stars aligning for Dusty to become IU's next coach.
From an IU perspective, yesterday felt like a win-win. Either DeVries succeeds and IU has its coach, or he doesn't and Dusty may eventually become a realistic option.
One other thing worth noting...over the last 30 years, only two coaches who left college basketball for NBA head coaching jobs have finished their NBA careers with winning records. The NBA is hardly a guaranteed path to long-term success.
