NFLers will retire if forced to stand for the national anthem?

I hope Colin Kaepernick and other NFL players follow the lead of Tennessee Titans’ player Rishard Matthews, who said he will retire if the NFL makes it mandatory to stand for the national anthem. Show us how serious and committed you are to the cause you profess to stand for. I and many others will not miss you — especially not as much as you will miss the high salary and media attention you have.
