New NFL Hitting Rule A Joke?

A new NFL rule aiming to cut back on head-to-head hits will be "impossible to officiate." This according to Former NFL V.P. of Officiating and current FOX analyst Mike Pereira.
Pereira said, "You'll see the same things happen with this as we've seen with the crown-of-the-helmet rule: very few calls. I think most of it will be taken care of after the fact with potential fines."
The NFL recently passed a new rule banning players from lowering their helmet to initiate contact on a hit.
