When using an Adjacent Slide defense the goal is to lock off the crease, denying the ball to the man in front of the goal. This is a great defense to run against a team who has a strong crease man.
bad idea to do this when there are two men on the crease because the adjacent slide would be much longer and the second defender on the crease, as second slide, should have a good chance of covering for the first slide.
If there is nobody in the crease the adjacent slide is the only option.
Force the midfielders down the alley when executing this slide package.
