Zoubek was the master of the hedge. When his man would set a screen for the guy with the ball, Z would step out and slow the guard down just enough that he couldn't drive, yet at the same time he'd know exactly when to get back to his man to not leave him open. Mason tries to do this but looks to me to be a little more lackadaisical, he just sort of sticks his arm out. With his athleticism he should be able to step out and disrupt the guard; I'm sure it will be a point of emphasis in practice
