We have a philosophy around here: Any time your opponent puts his hands on you, he gives you a scoring opportunity. It is a prevailing theme of our Attack System and we train it into our wrestlers constantly.
One of the key setups used, when an opponent uses his hands to try to work inside, is the Pull. If he gives you the inside position, we do an Inside Pull. If he goes inside, we control the elbow and do an Outside Pull (other options, when he goes inside, include an Elbow Pass/Two on One, Arm Drags, and Chops).
Here are a couple of keys to using the Inside Pull:
1. Pull Down, not up. When you pull up, your opponent reacts by bringing the arm down - not what you want. Pull down, and opponent forces back, bringing the arm up.
2. Level change as you are pulling. You always want to level change when you shoot, so if you do this as you are pulling, you will be in position to get under that arm and attack the leg.
3. Remember, circling away from the attack helps bring opponent's leg into you. I don't like to overdo it, though. Just 'drift', take about a step and a half and a shuffle, pull-down and level change, and you are in good position to attack.
