As has been mentioned, the single most important factor for an NBA coach is the buy-in of his players. Ime had it. Joe seemed to be lacking it last season, based upon the comments of a few players during and after the playoffs.
Now? There seems to be complete, unequivocal buy-in and respect:
That trust has been reciprocated and it was exemplified in the Celtics? roller-coaster Game 3 win, putting them one victory from raising championship banner No. 18. ?I think Joe is a basketball genius,? White said. ?So whatever he says, I?m going to try to just do it to my highest capabilities.?
Jaylen Brown on the Celtics coaches: ?The coaching staff has been fantastic all season long? it?s just been super organized, we walk through all different types of scenarios, we?re overly prepared.? On Joe Mazzulla: ?He?s been coaching his ass off.?
This has been my main point all along. Last season, the players got the rug pulled out from under them just before the season started. Udoka out, Mazzulla in. Boom. You go to practice one day Udoka is your coach, the next day it's Mazzulla. Same for the assistants. One day Udoka is your boss, the next day it is Mazzulla. What exactly would you expect under those circumstances? Total buy in?
This year, the players have had a chance to accept what happened and move on from Udoka. All of Udoka's assistants moved on and were replaced by people who wanted to be here. Mazzulla is not a perfect coach. I think it is fair to say that he is "ahead of schedule" as they say. But his team is probably going to win a title, in his second season as the head coach. I see that as establishing a pretty high floor under Mazzulla.
I don't know where to rank Mazzulla. Is the worst coach in the NBA still able to coach a really good team to a title? How about a top 20 coach, can a top 20 coach get a team toa title? A top 10 coach? Unless you don't think the coach matters at all, you have to acknowledge this as a pretty good indication of Mazzulla's coaching ability.
