The Volleyball/Basketball drill which is really a Football Drill

Have you ever done one of these drills? I originally learned this drill at Ontario Madawaska Volleyball camp in 1980, brought it to Saskatchewan (it was called the Alabama Breakdown...changed its name to the Cannell Breakdown and then I bring in a Hilltop(football)/Basketball coach to run a Basketball Defense session and look what he is running 40 years later.
