I think this is the Udoka's camp putting out spin to help him get his next job.
By skill alone as a coach, he should be an NBA coach. The questions come from non-coaching issues none of us actually know.
So, it is better for his camp the more they can put in the minds of other teams and fans of other teams that this is a case of the "Celtics overreacting."
I still think that the number 1 coach they wanted to hire who had more success in the his first year on the job then expected, is not going to be removed unless it was deemed necessary.
