The 3 attacking players move up the court, playing an unopposed 3 man weave all the way to the half court line.
Once they reach the half-way line they turn and play a 3 vs 2 back to the basket with the defenders staying inside the 3 point line.

Rebounding is the least glamorous thing in basketball and one of the most decisive. It is also almost entirely a habit, which means it is entirely coachable.
