This is the biggest knock early in the 2012-13 season.
The Celtics have a highly touted set of reserves and a new starter in Courtney Lee who just haven't produced yet. A lot was made about the talent Danny Ainge was able to bring in to rebuild on the fly. However, nothing has panned out just yet.
The Celtics are 2-2, with narrow, back-to-back wins over the lowly Washington Wizards, playing without their two best players. The benches of Washington, the Miami Heat and Milwaukee Bucks have run wild on the Celtics' group.
The Boston bench has been outscored in each game, with only Jason Terry starting to come on of late. This struggle has further facilitated the move of Jared Sullinger to the starting lineup. The move places a capable scorer in Brandon Bass on the second unit, and it has proved successful thus far.
Courtney Lee has been inserted into the starting shooting guard spot, taking the role of Ray Allen or Avery Bradley last season. He is averaging just six points per game, while shooting 22 percent from distance and 43 percent from the field.
The background of this knock is obvious; the Celtics return only four players, (excluding Bradley) from the 2011-12 season and only three remain from the 2007-08 championship team. That is a lot of turnover for a team that preaches lineup consistency as a major strength. However, it could be a weakness this season, as so much turnover occasionally leaves lineups on the floor who have never played together.
This leads to trust issues and confusion in roles, neither of which is good for Boston.
