The Knicks have too many good role players right now alongside Anthony
This gets to the heart of why I think the Knicks are a much better team.
Not only do they have the best player in the series -- Anthony, a superstar scorer -- they also have a number of effective role players who complement him.
The Celtics have a few good players. Pierce and Garnett are still quite good though no longer super stars. Green and Bradley are each capable of making a big impact in any given game, though not consistently.
The Celtics really lack reliable role players. Game to game, it's impossible to say what we're going to get from pretty much anybody on the team other than Pierce and Garnett. There are no rebounders, no "designated shooters", no primary ball handler, no "dirty work" guys. That's an area where the Celtics really miss Sullinger and Barbosa, not to mention guys like Ray Allen, Keyon Dooling, Greg Stiemsma.
