lol? so headlocks are bad because when someone who knows nothing does them against someone who knows grappling he will get beat?
That's like saying punches are no good because if an untrained man tries to punch an olympic TKD athlete and he kicks his head off that means punches are never good?
If a guy who knows what do do with a headlock, meets a guy that knows what to do against headlocks, chances are the one in the headlock wins the interchange because he has an advantage position.
