Not talking about the people who run the league but the folks who make the calls during the game.
The contenders:
- Baseball umps: Horrible at strike/ball calls which they botch constantly which is probably the worst call in sports. Umpiring has gotten better with instant replay in the MLB.
- NCAA Basketball refs: Tons of home cooking once you put them on another team's home court. Yet suddenly in the NCAA tournament they're able to call the game in a neutral fashion even if one team has 90% of the fans at a venue. Awful at consistently calling the same things within a game or over the course of a year.
- NBA Refs. Same as NCAA, plus the elite star players get massively protected. I do think the officiating is probably better than the NCAA at this point since it's gotten slightly better in the last several years
- NFL Refs: Actually pretty good and probably the best of the major sports. I don't really have a problem with most of the calls they make. Good uses of replay.
- NCAA football: Big-time bias towards the big school who can get away with holding and pass interference calls. Wild variation in quality between officiating crews & conferences. Some awful instant replay reviews and constant stoppages for replays.
- MMA refs/judges: Better that it was. Judging system in MMA is so awful that the judges can't do too much. With the refs you'll generally get some early/late stoppages that everyone complains about but there have been fewer screwjob finishes.
- Any "artistic" Olympic sport with judges: Seems like a lot of countries have judges biased towards friendly countries or their own participants
Sports I don't know enough about:
- Boxing judges/refs: Notoriously corrupt. Massive home cooking towards the local fighters by the judges as well.
- Soccer officials. Can have a huge impact on the game with yellow/red cards and they seem to be pretty hated. Constantly fall for people flopping
- Hockey: With all the penalties and power plays people have to get mad at them as well
- Auto Racing: F1 seems to have invisible unaccountable to anyone stewards. NASCAR just does shit to maximize entertainment value, fairness be damned. IndyCar has been pretty decent lately. I don't really follow F1 & NASCAR enough to know more than that.
