Simple 2 on 2 Rebounding Drill

The drill below is from the University of Arkansas.  A simple 2 on 2 rebounding drill.  I like how the coach also emphasizes making good outlet passes out of the drill.  

We will experiment with having our bigs stay on the ball, contest the outlook and look to chase and trap the outlet.  So, we will have our bigs chase down and breakdown on the outlet, simulating that they are trapping that pass.

If the offense gets the rebound, they get an offensive possession.  If the defense gives up an offensive rebound, they have to stay on defense with the next group.
