Cam Newton has been beaten, and battered throughout most of the 2016 season. Without a healthy o-line, Cam Newton appeared to have gotten hit the most last year throughout his whole career. The first Bronco game comes to mind when this subject comes up. The NFL, and the refs, appeared to not give any fugs about Cam whatsoever.
Now, egregious hitting to the head is an automatic ejection from the game.
Although refs are likely to ignore such in the case of Cam, it still is a small step.
