Seriously. I feel like QB should honestly have to take those hits and play through them. If you got hit in the chest it’s fair game. I prefer football with the added challenge of “if your quarterback isn’t tough he won’t play his best.”
I mean I get it for when people do it it with the crown of their helmet into the chest, but that was a clean tackle. Nobody would be injured from that
And even then like, that’s not “roughing the passer”. The QB doesn’t lower his head, only the tackler risks injury in that scenario
I think you could damage ribs/collarbone if it hit right, but for the most part you are right. They can’t protect the defense though, that’s a rule
