If what Doc said is true, this certainly doesn't make me feel any better about Ray Allen. If Ray thinks that he should have been the guy with the ball in his hands, creating offense, then he's got a really bad grasp on what's best for the team.
I would say that Paul Pierce would be more entitled to having that beef. And, I have noticed some friction between Rondo and Pierce as to who should be the primary ball handler over the course of this team's transformation into more of Rondo's team. They work it out, though, as best they can, on the court.
Over the past couple of seasons, however, Paul has consistently publicly stated that this is Rondo's team. The captain is a team player who has learned to sacrifice for the good of the team. Apparently, the same can't be said for Ray Allen.
