This is the standard way of defending the ball in the corner in a 2-3 Zone

• x3 puts pressure on the ball
• x5 fronts the low post and denies a pass
• x1 sags into the zone to make a pass or dribble attack for #4 difficult
• x2 is denying a pass to the high post
• x4 is ready to rotate on skip passes

This is the slightly more aggressive option. You deny the pass back to #2 and force #4 to make a decision. Only recommended if #4 is a weaker player with the ball.
