Not all of them are spineless. Jerry Jones has told his players that they will stand and not protest during the national anthem or they won't be on his team any longer.
If Roger Goodell had a brain, he'd ban all protests. There is no right to protest on your employer's time.
Maybe Jerry should treat quitters like Ezekiel Elliott the same.
Even easier, Goodell could tell the NFL and the announcers to STFU and stop broadcasting these morons on TV.
I start screaming every time some sideline reporter shows footage of the a-holes protesting.
Stop giving the protesters airtime and watch them dry up.
The only people who would then know of the tantrums would be the fans at the game.
