All-Pro Steelers linebacker James Harrison called NFL rule makers “idiots” today.

I’m absolutely sure now after this last rule change that the people making the rules at the NFL are idiots.
The 32 owners voted unanimously Tuesday to approve rules amendments for player safety, including a measure aimed at keeping a player from launching himself into a defenseless opponent. A 15-yard penalty will result for anyone who leaves both feet before contact to spring forward and upward into an opponent and delivers a blow to the helmet with any part of his helmet.
Such tackles will also be subject to fines.
The definition of a defenseless receiver already has been extended. Now, a receiver who has not had time to protect himself or has not clearly become a runner even if both feet are on the ground is considered defenseless.
Defenseless players cannot be hit in the head or neck area with the helmet, facemask, forearm or shoulder. The definition of such players now includes those throwing a pass; attempting or completing a catch without having time to ward off or avoid contact; a runner whose forward progress has been stopped by a tackler; kickoff or punt returners while the ball is in the air; kickers or punters during a kick or a return; a quarterback during a change of possession; a player who receives a blindside block from a blocker moving toward his own end zone.
