I agree that the "targeting" call is out of control and inconsistent. However, I've never seen anyone called for unecessary roughness for making an ankle tackle unless they were trying to purposely twist their ankle and break it.
They weren’t for those QB’s back then. Ask Joe Namath.
I liked a comment Joe made when at the University of Alabama. His friend said "the girls in the sorority are really talking trash about you." Namath answered "at least they're talking about me"
