Rick Carlisle's whole thing seems to be that he wants to call the plays and he's had personality clashes with the more creative improvisational PG types because of it. I remember the Mavs gave up a first round pick and a few of their better youngsters for a half year rental of Rajon Rondo when he was coming back from his injury and the last piece of the championship team left on the Celtics and things went so poorly that Rondo basically got benched in the playoffs that year.
I also think it's funny that Indiana keeps cycling through these head coaches who all prefer a similar style of structured half-court offense. They get impatient after 4 or 5 years of being good enough to make the playoffs every year but not good enough to make the Finals and they fire them only to bring in another guy who is just like the guy they fired. Bringing Rick Carlisle himself back is almost too on the nose. I guess they can't help what they are. The desire for change is there but they always circle back to what's familiar.
