Let's not focus on whether or not you feel the initial contact with the offensive and defensive player is a foul or not. If you can't help but to focus on that, the offensive player doesn't extend his arm past his elbow while the defensive player embellishes trying to draw a foul. However, the contact that occurs next by white 14 is the focus of this clip. He is able to land and then decides to wrap up the offensive player from behind. This contact is not a basketball play and falls into the excessive category. The lead official immediately recognizes this and signals for a Flagrant 1 (NFHS = Intentional) foul.
