Remember that time the lowering the helmet rule was going to change the way that the game of football was played forever? Well, the NFL actually has not given up on that plan. Only they are not going about it in the way that was predicted.
The assumption was actually that there would simply be a barrage of penalties—perhaps a dozen or more per game—until players started getting the idea after losing tens of thousands of dollars in fines, and in the preseason it almost seemed as though it would go that way.
Through six weeks, however, the lowering the helmet rule has only been flagged six times.
