Let me ask this: same play, same movements, except in this case, the ball carrier strapped on his lid, and it doesn't come flying off. Now what?
I think you guys are getting suckered into a flag because the helmet came off... I see no targetting. I do see a hell of a hit, and the ball carrier wasn't prepared for it, yes, but I do not see helmet-to-helmet, nor do I see launching. I see a tiny bit of body-moving-upwards, but not in a way that suggests anything other than a human motion delivering a natural blow.
