NFL

I’m new to watching sports in general, but every week it seems like something around the league is dysfunctional. Whether it be players being fined for seemingly minor things (like cheetahs peace sign), or bad referee calls, or organizations giving up, or how the trade deadline was boring compared to other sports, it all seems like the nfl is not very well regulated. Is this how it’s always been, or have these problems gotten worse as of recent? I’m not trying to put blame on anyone here, but what’s the underlying problem? Also, do these sorts of things happen in other sports all the time?
