It has to be tough being a referee in professional sports and not for the reason you are probably thinking of. Referees can't have a favorite team in the sport that they work in. You would think that a football referee had a favorite team growing up and that's why he wanted to be a referee in the NFL. How do you get a job in a sport you love and just not like any teams anymore? Also what makes you want to become a professional referee anyway?
I mean umpiring your son's little league team is probably fun but what's the incentive to going pro? I could never do it. I would want to watch the game and not my section of the field. That's the other challenge, is having a section of the field to watch during the whole game and not sneaking a peak at the actual play. Obviously I'm centering around football because that is what I mostly watch. I guess it's all about ethics and doing your job. I think the refs are underrated. I wonder how much they get paid? Are they under contract too? These are the things that I ponder everyday.
