I don't like it either. A person can't complain about "cancel culture" and like that billboard without being hypocritical, because that billboard is the epitome of what "cancel culture" supposedly is.
I'm not fussed about the billboard, if anything I think it's funny and surely a HC of an NFL team would have a thick enough skin to ignore stuff like this.
It's not at all 'cancel culture' though is it? It's just plain old sports fan stuff - if we can't call the coach a bum and tell him he should be fired once in a while then what's the point?!! :D
Cancel culture is when someone gets called out and ostracized because of some cultural belief or action - not being bad at your sports management job - and I'm staying away from discussing the merits or failings of all that. (K!)
