No one player is untouchable I'm sayin they would be strong in numbers. The Nfl couldn't suspend them because sitting the anthem isn't against policy. And they can blackball 20/30 of the nfl's best players
Maybe not, but this is the same NFL that'll just throw out random players out there during a strike and threw the whole officiating union in the bushes.
I see what you're saying (I responded thinking you meant only one player) and yeah, if a group of thirty or so players got together that'd be something, but this NFL machine is a different animal. I mean, the NFL has people literally out here saying that CTE isn't real and that you don't get concussions from playing football.

This country loves itself some football. Sadly though, if there were players sitting out to make a movement it'd probably have to be some white players too.
And these same players won't come together to do things to strengthen their own union, so I don't think they'd be willing to come together for a real cause.
