re: Nick Ruffin Hit

My issue with the rule lies more in the fact that the defensive player is at the mercy of the offense. If the offensive player decides to duck or lower his head as the tackle is being made, then the defensive player is screwed because he's now "targeting" the head or neck area. Defender are lining up a hit, then the location is being changed mid-tackle from a duck or lowered head and there is nothing they can do. And offensive player can lead with there head, but a defensive player can't? Just doesn't make sense to me.
