The single thing bothering me the most is the lack of chemistry on this team. The pieces just do not seem to be fitting together smoothly. It is possible Doc's ever changing lineups and rotations contribute to this. Players need to have defined roles to develop consistency.
There are a handful of guys who have no idea what to expect game in and game out.
Lee - is he starting or coming off the bench. Will he play 10 minutes or be asked to give 25+ ? Who will he be playing with in the backcourt?
Bass - is he starting or coming off the bench? Will he play 30 minutes or 10? Who is he going to paired with... and this is really important here because his role changes based upon which of the bigs he's asked to play along side.
Sullinger - Is he going to start? Is he going to play 8 minutes or be asked to go 20+? Is he a center or a PF? And this is being done to / asked of a rookie.
Even Jason Terry... is he starting or coming off the bench? Limited to 20 really solid minutes or asked to play 35 ragged minutes? Paired with Rondo or asked to lead the second unit?
Barbosa has no idea if he will play, play for 3 minutes or be given 20 minutes any given night.
Jason Collins went from DNP-coaching decision to starting center with next to nothing in between.
The need to rest Pierce and Garnett is recognized and a plan is in place to do so with KG yet they rack up more minutes than Doc would like to give them? Mind boggling when Doc is the decision maker on this. The expectation of players like Green and Lee seems to be for perfection they have such a short leash, but Terry can go 1-14 and have plays drawn up for him at crunch time?
There needs to be some consistency in roles to allow team chemistry time to develop. It cannot all be about waiting for Bradley's return. Bradley playing is not going to suddenly transform this team into a well-oiled title contender. Green and Lee especially need to be consistent positive contributors for this team but they need well-defined roles with consistent minutes to develop into their roles - something neither has gotten to date.
Starting line ups, rotations, playing time.... that's on Doc. He has to stop thinking "versatility" and establish lineups, rotations and playing time. Then versatility can emerge and take care of itself.
