I’m leaning more in the other direction.
The NFL is at the end of the day in the business of not just football but entertainment. Let them do backflips and point and glare at whoever so long as they aren’t hurting anyone. Build up rivalries. I do kind of miss waiting for things like a hidden sharpie or other creative, well-thought out celebrations. These guys give their bodies to make crazy plays, so why not let them celebrate to the max?
I will say while I hold the above view that I think if the NFL did allow more extreme celebrations it would make those who do act like they’ve been there 100x before look even cooler.
