MIAMI — Gabe Vincent drilled another 3-pointer after Marcus Smart missed another layup to give the Heat a 23-point lead early in the third quarter, and Jimmy Butler kneeled at center court, signaling for a Celtics timeout (which rookie coach Joe Mazzulla called for once). It was the same taunt Al Horford tried earlier in the Eastern Conference finals, before Boston blew its first of consecutive 12-point leads to open the series.
At the same time, Miami wing Max Strus drew a technical foul for taunting the Celtics.
