Well, the week 1 RTP wasn't arguable. He slammed his helmet into the back of Trubisky's helmet. Classic dirty Clay Matthews play. That's a penalty before this new rule. The other two are dumb. I can kind of see the Alex Smith penalty because he pile drives him into the ground, but Alex Smith had the freaking ball. That should nullify it considering it wasn't an illegal hit otherwise.
Obviously the NFL is targeting Clay Matthews. His history of dirty plays and the fact that nobody thinks he didn't use steroids must have something to do with it. Other players haven't been flagged for similar hits this season.
