Marcelo explains to Sou that he is making a common mistake when he tries to break free from Collar Control. You can't repeatedly tug at his wrist and expect it to come off. You have to yank his hand off in only one jerking motion, not several. Marcelo shows Sou that he incorrectly trying to break the grip with two pushes. Sou then correctly breaks Marcelo's grip, not by telegraphing with two short yanks, but with one strong, swift break. Marcelo goes on to say that this solution to the Collar Grip becomes complicated once an opponent is able to grab behind your back too, so don't let this happen. In jest, Sou suggest perhaps striking to make his opponent release the grips in this scenario.
