The Celtics failure was a team wide failure with blame to go around to everyone. Kyrie, in no way, shape or form was this team's only reason for underperforming.
While this statement is true in an absolute technical sense, I'm not sure I accept it qualitatively. It is the sort of statement that whitewashes the tremendous disparity in responsibility that different characters had in this drama.
A guy like Yabu or Wanamaker simply can't be compared to folks like Kyrie, Al, Stevens, etc., when it comes to the impact that they had on this season.
Kyrie shot the most shots, controlled the ball the most, was second most in minutes, made the most public comments -- whatever measure you want to use, he was overall one of if not THE most influential player on the team. If the season had gone well, he would deserve the majority of the praise. And because the season didn't, he has to take the majority of the blame. That's just the way it is.
I agree, though, that he has some company. Certainly Ainge and Brad have to be at least as influential on the season as any of the players.
I think Brad really handled this season poorly in many ways. But at least he has publicly owned that he doesn't think he did a good job. He called himself out as having made mistakes and needing to learn and improve from it. So people seem to be willing to back off from flailing him.
If Kyrie had the means of speaking in public in a way as to own his responsibility without hedging, waxing mysterious or throwing others under the bus, I suspect that would go a long ways to improve fan impression of him. But I haven't seen much sign of that from him yet.
To bring it back to the thread: I don't really see the point of getting too bent about Rozier. He was the third string small guard who was far too often asked to play as a small wing - a role he has sucked at for two years straight now. While he sounds like a tool to be complaining publicly, I don't really blame him for being frustrated. His career is at stake and he's been shoved into a wrong-shaped role.
In the end, he's most likely going to get picked up by another team so to me that's even less reason to get all worked up about him.
I'm far more concerned about the problems being surfaced by what he has said. That comment about them practicing one way and then abandoning that when they'd get on the game floor was very disturbing. Was Stevens that out of control of this team?
