NBA Analyst, and former Celtic, Kevin McHale called the 2016-17 Celtics team "the little engine that could." Kevin suggested that the Celts overachieved, in part, because of the bulldog defense provided by Avery Bradley and Jae Crowder. Kind of hard to argue with that. Those two starters played big minutes and and were counted on to hound key opposing players.
Boston, we have a rebounding problem. We finished last season rated 26th (tied with Indiana) in total rebounds/game. Al Horford was our top rebounder at 6.
