As of Thursday morning, the most three-pointers a Celtics team has ever made in a single game was 19. In their victory over the Bucks last night, Boston cruised right by that record on their way to net 24 total threes in the game. In other words, they broke the three-point mark by more than a 25% margin.
Led by Kyrie Irving's six treys, Marcus Morris' five, and Al Horford's four, the Celts rode the three-ball all night long.
It's a trend that the whole league has caught onto. If you look at three-point shooting at a league-wide level, team level, or individual level, every record is being re-broken.
