Like 40 games into last year i realized the guy only cares about shooting three pointers. If the Celtics make and attempt more threes than the other team he thinks they played well. Mazzulla has them playing like the Rockets teams that never reached the finals. Iso and drive and kick repeated over and over. No motion or off ball screens to get guys open looks like the Warriors and Heat do. Also for a coach who obsesses about the three ball so much, the team gives up a lot of good looks from deep.
Great teams can overcome bad coaches but Mazzulla is a really bad coach. Udoka has a terrible Rockets team 4-3 and the 7th best defense when they couldn't stop anyone last year but he spent years as a player and assistant learning. Not just getting a job he didn't deserve with an arrogance a lot of analytics heavy people in sports have
