The biggest reason I like the new rule is that it sets a good example to younger players. When kids see stars such as Rasheed Wallace of the Detroit Pistons shouting at the referees and arguing every call, they think it's part of the game. But shouting at referees and arguing calls should never be part of any kid's games. Kids should be taught to forget about the referees' calls and pay attention to improving their skills and play their best.

　　All players need to learn that you control only one thing in a game, and that's your own performance. You can't control what the other players or trainers do. And you certainly can't control the calls the referees make.

　　Finally, everyone from NBA all-stars to 8-year-olds should remember that being a basketball referee is a hard job. The referee has to make dozens of sudden calls. No hesitation. No second chances. Not even the best referee gets every call right.

　　Maybe if the players, trainers and fans who shout at the referees had to wear a whistle and call a few games, there wouldn't be as many complaints about the "zero tolerance" rule.
