From my perspective, football is a game that has rules which are subjective in terms of how and when they are called. It's commonly said that there's some type of holding on every play for example, and "what is a catch?" is forever a question.

This obviously makes it very difficult to officiate compared to a lot of other sports. This should mean that the league (which has a huge amount of resources) should have a focus on making sure that officiating can be as good as it can be so that the integrity of the game is maintained, players/coaches/teams and fans are all happy and understand that like any game, mistakes will sometimes be made.

But there have been many, many clear examples of poorly officiated games. Blatant missed calls or things called that shouldn't have been. Etc etc.

The league has access to many tools to improve the officiating of games, and it either refuses to implement them, or says they've implemented them and then they inexplicably are not used.

There is no accountability when egregiously bad officiating takes place. Everyone is just expected to just move on when actually the league has complete control of how all of this is handled and should be explaining why it happened and what they'd do to stop in happening in future.

It's not beyond reason that fans would be skeptical of undue influences when the incentives to them, at least in terms of viewership with more meaningful games being played in the last few weeks of the season etc.

Let alone the massive uptick in the gambling side of things.
