The part that has never made sense to me in regards to defenders trying to light up the opposing players is that it isn't good football technique. I couldn't begin to count the number of times I've seen a defender try to crush a running back or receiver and either bounce off or miss completely. Instead of using one's body as a battering ram, how about using one's arms to actually TACKLE the opposing players and prevent them from getting more yardage instead of just trying to hurt them?
