So the big complaints about Joe Mazzulla was calling time outs (at least that was the first thing). I think that is more less resolved. He figured it out. I think he probably still thinks the players should be able to play through cold spells more than maybe the players think that or "conventional wisdom" thinks that, but it appears to me he has accepted this. I don't see this as an ongoing issue.
Now there is this thing about emphasizing defense over offense, and to some extent, whether to start Derrick White or Rob Williams. It is true that we had the 2nd best defensive rating in the league but our defense was not as good as last season based on the eye test and statistically (110 vs 106 DefR). But we also had a very predictable offense last season and only got a little better statistically this season. We are still very predictable offensively and this allows teams to dial in on us, especially in the playoffs. I actually don't think there is anything to this. Of course the players and the coaches want to have a defensive mentality. But we also need to have some nuance and complexity on offense to make it easier on our stars and everyone else to score.
I think this is more about buy in. I don't think the assistant coaches who got left behind by Udoka and passed over by Stevens naming Mazzulla were fully bought into Mazzulla and I don't think the players got over Udoka and bought into Mazzulla. If this isn't fixed, the problems will not go away. If this air has been cleared, the assistants who didn't want to be here have moved on, I think Mazzulla will be fine. I think Mazzulla understands that the defense needs to be good.
The one thing I will say that does worry me is that there is more to offense than jacking up 3s. Our offensive schemes do need to be worked on. Off ball movement. Off ball picks. Curls off double screens. All of this should be happening at the same time. I think Mazzulla got the team back. I think Mazzulla will coach defense. But he now has a full off season to figure out some better offensive schemes. He needs to do that.
