Definitely agree that the running back scenario should never be called.I hate the targeting rule. I know it's in place for player safety, but the enforcement of it seems to be all across the board, and sometimes things can't be avoided.
Not a particular game, but a defender goes to tackle and has his head lowered and should go to the side of the ball carrier (think in the arm pit area). The defender is committed and in the process of the tackle. But the ball carrier slightly turns his body and lowers his head, and next thing you know, it's helmet to helmet and the defender is called for targeting. But he had no chance of avoiding the hit because where the hit happened was because of the actions of the ball carrier.
But I support blatant,unnecessary head to head blows to a defenseless player being called.
That was the situation on that play-it appeared to result in a concussion.
