I understand it. But, at the same time, does this have to become the new en vogue thing in the NFL... anytime a guy gets concussed, they cancel the game? Where do you draw the line? Hamlin - we all get - that was unique, he died on the field. But, what happened to Bolden happens a lot, where guys get knocked out cold, they do all the neural/spinal protections and cart him off. I'm not being callous, I'm genuinely curious, where do you draw the line with when to end a game? I only hope this was because it was preseason
