"Larranaga will be head coach for Boston's three-game stint in Salt Lake City, while Shrewsberry will take the baton for the duration of the Celtics' stay in Las Vegas. The reason for the split? Celtics head coach Brad Stevens doesn't want to burn out Larranaga…The 40-year-old Larranaga, Boston's top assistant and widely regarded as a future head coach at the NBA level, has led the summer squad the past two years. Shrewsberry, 38, who served as an assistant under Stevens at Butler University before joining the Celtics from Purdue University two seasons ago, gets a chance to step a bit further into the NBA spotlight."
Seems like a win-win situation for all involved. Both assistants get to taste what it feels like to call all the shots, and Brad Stevens gets to rest up a bit.
