Agreed. The discussion of "boring offenses" is way overblown. I see 2 actual legit concerns with that: 1) champions generally have top 10 level O/D efficiencies. That's not to be ignored. 2) will good players want to play in that system? Personally, I'm not as concerned about this, because good players are good players, and NBA types will sniff them out. If they're that concerned about getting to the NBA, then they might not be the guys that you can build a champion team around anyway.
Personally, Hoosier fans will get behind any coach who wins, and I think most Hoosier fans appreciate great D and effort.
