A rule preventing running backs from lowering their head into tacklers would be one of the most ridiculous rules ever. How can you play running back without being able to lower your head into defenders especially in a pile to try and gain yardage?

Would love to hear the opinions of Jim Brown and John Riggins on this proposed rule. Earl Campbell made his living lowering his head into tacklers.
There was even talk a few years ago about penalizing RB's for using a stiff arm to the face of defenders that looked like a punch. MB3 was doing that which got the league to discuss it. Player safety is important but penalizing an RB for lowering their head into a tackler is going way too far. Could you imagine an RB lowering their head to pick up a yard on a critical 3rd and 1 in the final couple of minutes of a championship game and they're penalized wiping out a first down.

No way does this rule pass.
