Former Mountaineer Joe Mazzulla has coached 100 games for the Boston Celtics.
After those 100 games, Mazzulla ranks as the winningest coach in NBA history with a .710 winning percentage which for coaches who have coached at least 100 games in the NBA, is the best mark.
Only one coach (Adrian Griffin) has a higher win percentage of .722, but he has only coached in 18 games as the first-year head coach for the Milwaukee Bucks.
