I saw no problem whatsoever with what Our Captain did after hitting that big shot last night.
If that was in fact his celebration, that is far more classy than say - what Kobe would've done. Look at some of Kobe's game winners over the years - he has a sort of "air" to himself - arrogance.
Paul Pierce? Last night, I saw a warrior that had just carried his team to victory - no arrogance whatsoever. He even laid claim to this "Newfound" rivalry that NY and Boston seems to have (Which ESPN did a good job in creating over the last few days).
In the post-game interview, he stated that NY is definitely a competitor in their division - what more does NY (and Spike Lee

) want to hear?
Do your thing, Captain!! Fly like an Green eagle!
