Circle the Wagons is one of my favorite rebounding drills. I originally got this drill from Coach Donovan while I was at Florida. Jay Bilas also went over this drill at last summer’s Coaching U Live. It creates a competitive environment and really challenges both the offense and the defense. To make it competitive, the defense must get 3 (or 5, whatever number you would like) perfect block outs and give up no offensive rebounds before they can get out. This will really encourage your offense players to bust their tails to get offensive rebounds.
