Detroit Lions review: Roughing the passer calls, not being made. This guy is going to end careers!

Aidan Hutchinson jumps on QB'S backs and then pulls down with his full body weight, that's a penalty! According to the NFL’s roughing the passer rule, a defender cannot bring their full body weight onto the quarterback after he’s hit 1. Doing so will result in a penalty. I've seen Hutchinson do this at least 20 times this year and get away with it! That's not a legal tackle! Is the NFL going to address this?
