With some athleticism and solid coaching, young offensive players find success early on by making one hard dodge and running full speed toward the goal.
As players mature both in skill and lacrosse IQ, defenders become more proficient at defending single dodges and/or team defenses learn to thwart athletic offensive players with effective slide packages.
The immediate answer is to draw the slide and move the ball faster than the defense can recover to the back side, opening up another teammate for a shot or dodge against a late recovery and potentially poor approach.
