In case anyone had any doubts, and you probably didn't, the answer is "yes." According to CNN, NFL ratings are down, people are demanding refunds, and "taking a knee" is "a factor." While there are undoubtedly other things contributing to the decline in viewership - cord-cutting chief among them - they don't explain the refund requests. It's a safe bet that a bunch of millionaires throwing an anti-American tantrum is turning off a lot of former fans.
From CNN:
“I’m told the owners have research clearly showing the president is right when he says the anthem protests are one factor in a TV ratings drop, and since the president weighed in—the owners are now dealing with a surge in ticket holder requests for refunds. Other sports leagues are watching this quite closely.”
Anyone shocked? No? Good. This is 100% unsurprising. Why would anyone want to pay exorbitant ticket prices just to boo a team that's slapping them in the face?
The question now becomes: "Where is the tipping point?" How much good will and revenue is the National Football League willing to sacrifice to its politically correct agenda? The NFL is a business. When will the lost dollar signs overcome the owners' fear of upsetting their players?
