Everyone who watches sports, plays sports, used to play sports; they have all had problems with officiating. Fans and athletes (humans in general) are inherently biased. If the 49ers have a pass interference penalty called against them, I ignore the actual rules and list all the reasons why Nate Clements was not at fault. Naturally, if it’s called against the other team, I comment on how fantastic the officiating has been this game.
Major League Baseball may be the toughest league to umpire in, and despite being harshly scrutinized, statistics show that MLB umpires do an unbelievably accurate job making calls every season. Still, one missed call can change an entire at-bat, which can change an entire game, which can change an entire series, which can change an entire season. But, human error has been a part of the game forever and despite the possibility of the expansion of instant replay, I highly doubt that umpires will ever be completely replaced by emotionless machines.
