There really isn't a reasonable counter argument to be made here. Kind of surprising people are trying to make one. No matter what sport you are playing, individual or team, if you are already winning be a gracious winner and show good sportsmanship. You can be excited as all heck at the end when you win, but in the middle of the game showboating and running up the score is poor form. There is a reason baseball teams stop stealing bases up 10 runs, football teams put in their backups up 4 touchdowns and bball teams clear the bench. You add in the fact these NBA players making many millions of dollars, have access to better coaches, training and other resources and are expected to dominate and it makes the celebrations and score running even worse. Finally, as much as we hate to admit it, kids look up these guys all around the world. We don't need to see them being taught that taunting your opponent no matter their skill level is great and cool.
