Celtics coach Joe Mazzulla borrows NFL tactics in preseason play

BOSTON — While many coaches stick to a specific style of management over the course of their tenure, Boston Celtics head coach Joe Mazzulla isn't afraid to try new things out. It even seems like he enjoys incorporating different philosophies into his coaching and actively seeks out opportunities to learn from other perspectives. And the fifth-year head coach literally took on a new perspective during Boston's preseason opener against the Cleveland Cavaliers on Thursday night. Instead of coaching from the sidelines like usual, Mazzulla had two of his assistant coaches, Tony Dobbins and DJ MacLeay , lead the way.
