Robert Williams III delivers for Celtics, Joe Mazzulla in do-or-die Game 6

Key Facts

His Boston Celtics had just knocked off the Philadelphia 76ers in Game 2 of their Eastern Conference semifinals matchup, and Mazzulla, aware of the public criticism being lobbed at him — that, as a 34-year-old first-time head coach, he was unprepared for this moment, and more specifically, that he was failing to make the proper in-game adjustments —wished to make a point.
One of the top rim protectors in the league, a player whose presence on the court and chemistry with fellow big man Al Horford helped catapult last season’s Celtics to the Finals.
With Williams lurking, Harden — who finished with just 13 points while misfiring on 12 of his 16 shots and turning the ball over five times — had no lane to the hoop.
Rivers also might counter by removing Tucker from the lineup and inserting another shooter — during his postgame press conference he singled out Georges Niang’s Game 6 performance as one he was proud of — which would force Williams to either spend more time on the perimeter or guard Embiid.
