You really don't know how one could make a semi-credible argument? Really??
I'll go with a simple one, officiating frustration in football is probably higher than any other sports I've been following, it's not even close. It seems like about 1/3 of the games there is major officiating controversies. Everybody is frustrated, fans, coaches, players, announcers. It's crazy. Calls are super inconsistent game to game and even within the same game. Blatant fouls are ignored and phantom calls are made every game. They are actively ruining games, which is the worst possible outcome for officiating in any sports.
NHL referees are a non-factor in maybe 98% of the games. It's pretty exceptional that I watch a game and I'm frustrated with officiating. I think they do a really good job calling the game most of the time and letting the player play and keeping the game under control without being a factor. NHL has started reversing their own calls as well, mostly on high-sticking calls. There is room for improvement of course but overall I don't have much of an issue with NHL refs. My biggest beef would probably be in the playoffs when they get too afraid to make calls and ignores blatant fouls.
