The new rules about "protecting the QB" is pure BS. I have seen over a dozen calls this season where literally a linebacker or defensive lineman touched the helmet of the QB and it is flagged for 15 yards. This is not including where a defensive players momentum hits the QB. What a crock! It ruins the game of football unfortunetly.
Late hits and the "intentions" to hurt the QB is pretty obvious and what they call nowadays makes it almost impossible for defenses to pressure the QB.
