A lot of good the new safety rules did for Nick Chubb's knee. What a bargain that was if you're the Steelers. Take out the opposing teams best player, maybe forever, and all you get is a 15 yard penalty. Great job making the NFL safer.
Want to make the NFL safer? How about making it a illegal to go for a player's knees if he's stacked up at the LOS and has lost all his forward momentum. Or at least make it legal that if he does, we as fans can go into the field and behead the bastard.
This is a barbaric sport, go back to the old rules and let these guys have at it, or put flags on them. They already effectively took away jobs of returnees like Devin Hester and Josh Cribbs who's main skills were returning kicks.
