Coaches are always scheming to create tactics to give them a numbers advantage. One of the best ways to create a numerical advantage is to switch the point of attack. Many coaches will attempt to do this in the air. In the video clip below Brian McMahon,Palm Beach Atlantic University Head Coach, demonstrates the Channel Game. This is 5v5v5 drill that he uses to switch the point of attack on the ground.
This drill is from a complete DVD on shifting the attack. For more information about the DVD click the link Switching the Point of Attack
