After listening to Damian's backcourt presentation yesterday, I am sure you will have no difficulty with making a call on this video play.

A1 is dribbling in the backcourt. A1 passes to A2 who jumps from the frontcourt, catches the pass, lands in the backcourt and then loses the ball. A ball which is in flight retains the same location as when it was last in contact with a player or the court. (4.4 Art 3) So the ball had frontcourt status when touched by A2 and backcourt status when A2 landed with the ball. Clearly a backcourt violation. I think the Center official should have made the call.

Now let's take the same play and say that A2 muffs the ball while in the air, still jumping from the frontcourt to the backcourt. If you look closely, A1 was the first to touch the ball after the muff. Still a backcourt violation. A player shall not be the first to touch the ball after it has been in the team control in the frontcourt, if he/she or a teammate last touched or was touched by the ball in the front court before it went to the backcourt. (9.9 Art 1)

Last option: Take the scenario above where A2 muffs the ball in the air and B1 then beats A1 to the ball and is first to touch it. No violation would have occurred.
