From an interview Pierce did in Spain recently:
Q: Is Kobe really the best player in the world?
Pierce: I don’t think Kobe is the best player. I’m the best player. There’s a line that separates having confidence and being conceited. I don’t cross that line but I have a lot of confidence in myself.
I guess it's a good thing to have confidence, but despite what Pierce (and Ryan Hudson, our own resident Boston fan) might think, it comes off as conceited. Pierce had a great season, and an even better playoffs, but sorry, he's not the best player in the NBA.
