yes, i doubt very many players purposely want to end a guy's career. I'm not saying these guys are evil, but I would say most of these defensive players and coaches know that it's just a necessary risk in order to become a respected and feared defense. Their job is to put fear, pain, and hurt into the opposing offense to give themselves an edge and if, by doing that, an injury occurs, it's not going to stop them from doing their jobs. To me, that qualifies as hitting with the intent to injure. I'm not saying I disagree with it because if I were a defender or a coach, I would be preaching the same thing to give myself an edge.
