So to me, I have been saying all along that worrying about TOs is frivolous nit-picking. He is not going to be fired, nor should he be, over that. He is already adjusting. I think many coaches are too quick to call time outs and then don't have them when they need them. It is kind of the same in baseball over taking out the starter. 2 outs in the 6th, a couple men on base, do you leave him in or take him out. If you leave him in and the starter gives up a hit, second guess, take him out, second guess. Mazzulla has his own philosophy on this but he needs to figure out what is going to work best for this group of players, and he is doing that.
What the team/organization needs to assess is the level of buy in that Mazzulla is going to be able to get from the players. It is apparent now that there were lingering issues with the players over the firing of Udoka, and not full confidence/buy in with Mazzulla. Comparing Mazzulla to Udoka, and so on. This was largely masked for most of the season by them playing well. To me (and I know some disagree with this theory), the combination of Udoka taking the HOU job, Mazzulla having kind of a bad couple of weeks coaching, the team playing bad, allowed this to flare up. They seem to have gotten over this, at least for now, but this is the big question.
This is not something that can be decided right now. It shouldn't really be impacted by how the next two games go. It is more fundamental than that. Is Mazzulla the right voice for this team. Some really successful coaches were let go recently by some pretty successful teams. Not because of Xs and Os (or TOs) but because those teams felt they needed a different voice. Mazzulla may not be the right voice at the right time for this team. That is what the Celtics need to figure out.
