Watch as Coach Grant McCasland explains and shows practice video of this 1-on-1 defensive drill. He describes his team as a "gap team" with the defender a step off the line, and all they're doing is recovering and not stepping toward the ball. The defender wants to be close enough to touch and lower than the offensive player. If you commit to the ball, you must take a charge or deflect the ball. Close on the shooter with either hand up.
