Lol why wouldn't it be?
You want people to be able to punch cats and claim they were aiming for the ball?
People be like "I'd never put my kids in football look at all the CTE, life altering injuries, job security, pension etc." then also "OMG this shyt is so soft, fukc Goddell". Not saying that a punch in the gut or throat will lead to a major injury, but it's dirty.
And they are obviously just targeting people doing it too aggressively i.e. like Campbell. If anything it's to avoid fighting, cause if I'm a receiver and someone keeps on punching me, I might black out and punch him back.
