New Rules Changing Game?

The NFL believed that there were too many injuries last year and are changing some rules to help prevent more injuries from occurring. One rule is to prevent defensive lineman from getting hurt. They are stopping what is called a peel-back block, which is pretty much a blindside block by an offensive lineman. Another rule is that punters will receive treatment like quarterbacks. No helmet to helmet contact with a punter or even an unnecessary hit when not in the play. The third rule is the elimination of what is called the horse-collar tackle, which is when someone tackles the ball carrier around the neck. With these new rules being in effect next season, do you think the NFL is taking away from the aggressiveness and excitement of the game by not allowing big hits?
