This ‘cross formation’ jump ball set is preferable when the tap is not assured and when a defensive jump ball is necessary. Essentially, if you think you may not gain possession on the tip, you set up in the the cross formation. This guard around play, however, is effective if you do gain the tip.
When the official tosses the ball up, O5 attempts to tap it to O2. O2 then hands the ball to O3 as O2 goes past and toward the basket. O1 goes right and O5 trails middle. O4 becomes the safety man.
O3, upon receiving the ball from O2, attempts to drive to the basket. O1 should be coming down the right side looking for a potential pass from O3. O5 will also be a potential trail option in the middle for O3.
