I know...it's morally wrong, and too much of it/going into the stands is very inappropriate, but NBA fights are what make the season interesting. Now that the TNT analysts started joking about "stick and move," the cowardly sucker punch thrown by Melo, I think it's safe to say this one has been dealt with and David Stern shouldn't worry too much about losing many fans.
I remember the coolest moments in NBA history being fight-driven:
Sir Charles taking Shaq out with his own sucker punch,
The Knicks-Heat brawl in the playoffs,
Malone-Rodman,
Shawn Braley being suplexed by that little guy,
I loved it all. This is America and we wouldn't pay for it if it were any other way.
