If he can get to that point, it’ll be more effective. If the opponent recognizes the setup early enough, he can simply duck under the arm as he’s initiating the headlock.
If he does get the throw, and if the opponent is halfway experienced, he’ll start rolling out of it before he hits the mat/ground.
Wrestlers generally stop throwing the head and arm after their first few months for good reason- it’s too easy to counter. Against someone who’s new, it works fine enough. In a street situation, sure, use it. But be prepared to get out of trouble if you mess up a little bit.
Rolling through...
