Ok, got another one. I am the trail. Team A has gathered a defensive rebound and is in their backcourt. Player A1 is dribbling the ball towards the division line, while team B is pressing. Player A1 passes the ball from his backcourt location to A2, who was located in the frontcourt, but is jumping and lands in the backcourt. A2, in mid-jump, taps the ball back to A2. Due to A2's previous location being in the frontcourt, I call an over and back violation. Is this correct? Does it matter if the pass-back is a tap or with two hand?
