NFL is about its paper....
This. Money will never take a backseat to tragedy or humanity. I guarantee most players heads probably will not even be in the game but I bet if the NFL threatens with some type of missed game=missed checks most would do a 180 on their moral stance.
<<The Standard>> hit on it a little bit in that a lot more than just the players would miss out on their money. The bigger the money involved the less respectful a business tends to be.
