A long, tough 2013-14 season has finally come to an end for the Boston Celtics. After a six-year stretch where they were contending for NBA championships, the Celtics entered into the first season of a rebuild and it was hard for fans to watch as their historic franchise limped to a final record of just 25-57. General manager Danny Ainge has done a wonderful job setting up his team with valuable draft picks and young prospects so we should not expect the Celtics to remain at the bottom of the standings for long. All was not lost in 2013-14 with young players emerging and a number of veterans showing they could be valuable role-players regardless of how next seasons’ roster takes shape. Here are the player grades for each of the 15 players who finished the 2013-14 season on the Celtics roster.
