I just re-watched the match. The penalty point assessed against Drew was for an illegal cutback. I have seen that called several times this year. Carter came close to doing one against Massa in the final. RBY also likes to do something similar. If you leave your feet to do the move they are going to call you. There seems to be an emphasis on calling it recently. Here is the applicable section. I was unable to include the photos from the Rulebook: No. 44—ILLEGAL CUT BACK. Wrestlers are not allowed to use their leg to execute a cut back, regardless of whether the hand is being used. Nos. 45 and 46—ILLEGAL REAR STANDING DOUBLE KNEE KICKBACK. A wrestler shall not leave their feet to block behind both of their opponent’s knees with one or both of their legs, feet or shin bones. Both photos demonstrate an illegal double knee kickback because the wrestler has left both feet in order to collapse behind the knees of the opponent.
