To arrive at the answer moving forward let's step back and review the past along with how NBA coaching functions.
Let's begin with the Head Coach who relies on his assistants to handle specific responsibility....Joe had Ime's second-row assistants as HIS right-hand men (kinda sub-optimal, no?). Blaming Mazzulla for this years defense completely 100% ignores the facts that we know (or should know if we are following) such as it was Mazzulla who ran the defense last year. Do we have this short of a memory to not recall that it was his defensive schemes which put him in the position to be a man of interest for other Head Coaching interviews? Pointing toward a couple of games following elimination wins as evidence of defensive breakdowns is kinda silly. There were multiple stretches in this game when the Celtics has the Heat offense shut down for 20-24 seconds and some of them ended with a made 3 as the shot clock was going off.
A quick 5-second search pulls up many stories of last year but here's one quote from Brogdon when he first arrived in Boston....
In a recent
interview with Bally Sports’ Brandon “Scoop B” Robinson, Celtics guard Malcolm Brogdon suggested it wasn’t Udoka who crafted Boston’s epic defense. Instead, it was current head coach Joe Mazzulla, who was promoted from his role as an assistant after Udoka’s suspension this fall.
Brogdon was traded to the Celtics this summer. He told Bally Sports he didn’t know much about Mazzulla prior to arriving in Boston. Brogdon explained he quickly learned his new coach may have been responsible for his club’s vaunted defense.
“A few guys told me that he was sort of the mastermind behind our defense and everything in the Finals, and his game plan, his adjustments, and his scouting reports were really good,” Brogdon said.
