As long as the team is winning and being successful AND Kanter is getting his 20-24 minutes a game, I don't think he is going to care whether he comes off the bench or starts.
But, if the team isn't playing well over the first couple months, and Kanter, in his mind is playing well, but either not starting or not getting enough minutes, then yeah, I think he could go all David Lee on this team. But by then he will be trade eligible so Danny will just move him.
