Quite frankly, the lowering the head rule on the defense is a well intentioned rule, but it is policed completely idiotically. The same will happen with this rule. With this idea that we must protect people from themselves in every sector of society society will decay. Just like the NFL has started to begin its end like boxing did for differing reasons. The simple fact is, that if you engage in a sport that is a full contact concussive sport (NFL, Boxing, MMA, etc.) then you must live with the consequences of participating in that sport. Yes, the player share the blame for it, but this is a societal thing. Its even a political thing now. There will come a point that even I will stop watching the sport. I have no interest in watching games that look like the pro bowl every week.
