Boston Celtics guard Marcus Smart will always go out of his way to make good defensive plays, and he doesn’t care who gets in his way. 

Even a referee. 

Playing against the Chicago Bulls on Monday night, Smart deflected a pass from DeMar DeRozan to Zach LaVine, and instead of going out of bounds, the ball hit off referee Marc Davis's head and stayed in.

Smart, recognizing that, sprinted over and tried to keep the ball in bounds. But Davis was once again in the way. Smart bounced it off his head for the second time instead of on the hardwood. 

Davis made the call that the ball was out on Smart, and they both smiled as both teams set back up for the inbound pass.
