If you go back and rewatch this game or most any other game, you can see "targeting" that is not called. The only reason it was called here was the guy fumbled and layed on the ground afterward.

If he fumbled and got right up, do you think there would have been a call? I can bet not.

I have seen plenty of plays where a guy goes low to tackle without wrapping up. The only issue this time was the ball carrier also went low with his head down also.

The hit on Cunningham was way more flagrant and wasn't called.
