You wouldn't believe the parents. One parent hounded me an entire game who was watching the game behind his son's team basket where the chain link fence is. A lot of my calls were guesses when it came to 50-50 balls out of bounds or fouls driving to the lane. It isn't like TV where you have all these multiple camera angles (The TNT Overtime Action view is very up close and personal you can see trash talk or what players are saying or signaling to each other. It is good for spotting missed calls but for the most part they get the calls right even incredible difficult calls) but the worst of it was the parents. I couldn't take 20,000 people screaming at my calls not to mention grown men & coaches screaming about calls.
In a different game that another crew worked the same parent that was at my game got into a heated exchange with the refs where I guess they gave him warnings (he would ask for fouls every-time his son drove in the lane -- who was a good player for his age btw) and it blew up and told my boss & other refs (we would work like 4 games at a time at outdoor basketball courts) "This is Mesa where white people stick together." I think it was true statement as there are a lot of racists east of Tempe but it didn't apply to the situation.
I have a lot of sympathy for professional refs.
