This is an incomplete evaluation. Kanter's substitutions were sporadic. It wasn't that he was only getting 27 a night, it was how he was getting them. Most offensively gifted players are rhythm players. If you don't have a rhythm that works for a player, or no rhythm at all, you'll upset their game.
Kanter was often pulled for his defense, but Trey never was until he lost his starting spot to Dante. There were other repeat offenders as well. If there was no Trevor Booker, Rudy could have gotten more minutes, which would have allowed him to play more with Enes, which would have allowed Enes to play more consistently. Rather than Rudy being someone who was gunning for his spot, Enes would have been in a position where Rudy's increased play helped his game.
