Has to be between NFL and NHL...I am going to go with NFL...How many times do these fucking refs make themselves feel so important to these games?
Going with the NFL also. Mostly because one bad call can change a game or 16 game season, more than the other sports. One game in the NFL could mean the difference between 1st and 3rd place in a division.
I think refs just generally suck in all sports, and they aren't held to high enough standards. It seems like most people think the worst refs are the ones in the sport they watch the most.
