As a fan, I'll be rooting for one of the teams, and like to watch some great basketball at the same time.
However, when I referee, I don't look at it the same. I honestly don't care who wins or who loses the game that I am working... because if I did, it would be a problem.
People ask me all the time "How can you handle being yelled at for the whole game... one team not happy with your calls, then the next team... back and forth, back and forth?"
Well, I'll tell you what... I don't see faces.
I see numbers on jerseys, and situations that happen before me between two teams.
I take a picture of the play (and continue to take probably thousands of "pictures" in a game), and try to make the right call (or non-call) ... as the game unfolds before me.
The focus should never be on the official. It should be on the players who play and are making the acrobatic (sometimes fantastic) plays with their teammates. The role of the official is to manage the game, the players, the coaches, and their emotions. Once your emotion becomes involved, it changes the way that you call the game... and then people start to notice.
That's why for tonight's game (as a basketball fan) I'll be emotional and really get into the game, because I have every right to.
However, when I come home from most of my games during the season, my wife always asks me "Who won?"...and I stop, think about it, and try to remember (because I really don't care who won)... and then once I really think about it, I give her the answer.
And that's why it doesn't bother me when I get yelled at. Basketball is a very emotional game. The fans, coaches, and players have every right to get involved in their team's success, just like I would want.
However, if they cross that "line"... then I'd have to take care of it... without too much emotion of course.
That's why I referee, because it builds character, teaches you how to listen, hear, and apply ... and how to deal with people.
