For those who believe that the play is legal if the ball bounces again in the frontcourt before the teammate recovers it:
A1 is trapped in his backcourt near the end line. He throws a bounce pass with spin that bounces OUT OF BOUNDS on the two-foot thick end line under the basket. A2 in the opposite corner of the court along the same end line in the backcourt waits for the ball to bounce a second time INBOUNDS on the court and then picks it up.
Do you think that this is legal as well?
