Look, it's preseason. Let's not be getting all dirty right now. Putting a forearm on Cam Newton's helmet -- kind of wrenching his neck -- while presumably giving him a quick talking to isn't really the route to go. Especially after diving onto the pile late.
But Muhammad Wilkerson did it anyway.
It's not terrible, but ... it's preseason. And Wilkerson didn't really do anything on the play anyway, other than fall on top of Cam late.
