The NFL was in an impossible position (they don't care about the substance of the protests) either piss off their employees which would cause an immediate problem, or piss off their customers which will cause a lasting problem. They made their choice hoping the latter problem will blow over, I don't think it will.
It's sad that this started over the hands up don't shoot lie that had its flame fanned by our former President. Pro-tip to protesters, when you incorporate manipulative shocking tactics like disrespecting our flag and anthem to draw attention to your cause it is transparent, and unlikely that the manipulated will have much interest in listening to what you have to say.
