Yes it is the new rule that is getting the defensive players hurt. Do you really expect them to be able to change the way they tackle a qb in just one training camp when their whole life they were taught how to tackle 

As long as the precious qb is ok they dint care about anybody else.  This league is getting way to soft. Just look at the penalty that clay Mathews got. He was trying to throw the qb on the ground.  He made a perfectly fine tackle and went trying to pile drive him or anything malicious, just a sack

I miss Pete and Pete! I would watch your version of it though
