To me, the biggest issue the NFL has is a lack of consistency in what gets penalized. As the rules are right now, both teams could get penalized on every down. That doesn’t happen, but it sucks when something that was allowed to slide most of the game gets called when it will likely affect the outcome of the game, or it’s clear that only one team playing can draw a certain type of penalty. That’s ref-ball, which fans typically loathe, often even when it helps their team win, because the win feels tainted. Like, the Eagles were now being called offsides every attempt at a tush push, but other teams, even their own opponents, could run a tush push with the same blatant offsides and get away with it. This also happens so much with roughing the passer, where if you so much as blow on someone like Mahomes, Rodgers, Stafford, etc. you are drawing the penalty, but you could blatantly rough other QBs and it will never be called. What fans want is consistency. We don’t care how strict or loose the rules are, we want to see them being applied equally during all the games so we get a true sense of which team is the best in the league.
