It is too violent, I hardly watch US football and in the few games I've seen the last couple years there have been 2 or 3 concussions that looked as much like someone dieing as this video, with apparent brain damage due to posturing while unconscious, as disturbing or more to me as this video. Most people there have probably seen someone fall hard and go unconscious, it's kind of fucked that they should be used to seeing that but I think that could be part it.
