The lacrosse scoop is a technique used to gain possession of the ball when it is on the ground. The scoop happens as a player moves toward the ball. It is the primary ball recovery technique when a ball is loose and on the ground.
In order to perform a quality scoop the player should drop the head of the stick to the ground and the stick handle should almost but not quite parallel parallel with the ground only a few inches off the ground. The concept is similar to how you would scoop poop (pardon the expression) with a shovel off the concrete. With a quick scoop and then angle upward to keep the ball forced into the deep part of the pocket and from rolling back out.
Once in the pocket the player will transition to a cradle, pass, or shot, and continue on.
therake and scoop is usually done when several players are fighting for the ball. As the ball is on the ground a player will take the back of the net and place it on top of the ball while quickly pulling the ball toward them. as the ball roll's off the end of the stick the player drops the head down to the ground and then let's the ball roll in using the momentum of the ball that was caused when they raked or pulled the ball back.
This happens very quickly and in one fluid motion when done right. They drag the ball back toward them quickly and then quickly shift the head behind the ball to scoop it as it rolls toward them. They then scoop and transition once again to a cradle, pass, or shot, and continue on.
