Now this I can do...maybe.

From eHow.com, "How to Perform the Perfect Swim Move"

1. As a down defensive lineman, you're already in your 4-point stance when the offense breaks the huddle.



2. Survey the offensive scheme. Determine whether or not a swim move is warranted. It's 3rd down and 14 - an almost guaranteed passing down. You decide yes.



3. Keep your eye on the ball. An encroachment penalty would be costly. Decide which side of the lineman you plan on performing your swim move.



4. When the ball is snapped, take the hand to the side you want to go, and use a boxing-style hook shot. Go around and shove your arm through the outside of the offensive lineman's shoulderpad. That should lift the lineman up slightly in that direction.



5. Use your other arm in a swimming motion over the lifted shoulder of the lineman, as if you were doing a crawl stroke over his head.



6. Run through the lineman's block. If timed correctly, he will never know what hit him.



7. Sack the quarterback.



8. Celebrate.
