Look carefully at the end of the Knicks' March 4 loss to the Celtics where Anthony congratulates Rondo and another Celtic after the game. What I saw in that embrace was not a man whose heart is with his team or teammates but rather someone whose heart is more interested in pursuing his own ego-centric personal agenda (of presumably making this "his team" again) or supporting the dominance of la raza.
What I also saw during several of Anthony's post-loss interviews since he returned to the rotation was someone just paying lip service about what they need to do better as a team, how Lin needs time to mature his game, etc. The guy wasn't speaking from his heart.
I'd go as far as saying that Anthony might be consciously trying to undermine the Knicks' success with Lin using underhanded methods. Take Anthony out of the equation and I think you'll see a much more cohesive and successful TEAM.
