Easy question. Whichever sport you love and watch the most always has “the absolute worst officiating”. And they’re always against your team!

I'm not a huge football fan, but I said football because one bad call can have such a devastating impact on the outcome of the game.

Like pass interference for example, awarding a team like 60 yards on a play they likely wouldn't have caught anyway, is just insane. Over questionable contact

There was a play like that earlier this year, that fed directly into a change in the lead after the benefiting team went on to score a touchdown. Then, on the next series of downs, for the opponent, the defender was almost climbing the intended receiver like a step ladder, with no call at all... And I was a wondering 'wtf?" made me suspect the game had been fixed, it was that blatant.
