If both Allen and Green are not getting shots, that means they are not part of the offence. That means selfishness is back. The Celtics are best when everyone is involved, especially good shooters like Green and Allen. Maybe Davis  needs to play more defense, and Rondo needs to grow up and become the conductor on the floor. He has good vision and good instinct, but not a great shot: give the ball to the guys who can score.
