On a team with a younger core, shouldn't the elder statesman with championship experience not change the offense without consulting the coach?
I think that's being blown way out of proportion.
Lebron and Kyrie were being too deferential to one another. At one point, Kyrie asked Lebron to take over. I can't remember what game that was, but the team won. Since then, the team has played better with Lebron being the primary ball-handler.
It's an example of players figuring things out for themselves. There haven't been any reports that Lebron openly defied Blatt (at least that I'm aware of). Rather, offensively, he's just taken the ball into his own hands more. While I agree that Lebron should be more open-minded and supportive of his coach, Blatt needs to take control of the team, and run a competent system. Right now, he's running his starters into the ground, and there's no coherent offensive or defensive plan being executed.
