This actually gets back to the point of this thread. Anyone watching NFL can see that the officials nether strictly nor consistently follow the rule book. They decide when to stick to the rule book and when to use their own judgement. It happens on nearly every play. This really isn’t debatable.
The question is if they do this in order to favor one team over another. In this game it was clear they were favoring the Chiefs over the Bengals. That makes sense and checks with NFL history. The league wants certain matchups, so they encourage the refs to help those matchups happen. We have seen this constantly throughout NFL history, going way back.
I can understand why you, as a Steeler fan, don’t see this, because for as long as I have been alive, the Steelers have been one of those teams that the NFL favors. You’re not seeing the bias, because you have benefited from the bias the whole time. It’s like a nepobaby in Hollywood claiming that there is not favoritism towards family members of famous people. They don’t see it because they benefit from it, it’s just their normal way of life.
