This is just something I do at our local rec-ball field. Down the left flank there is a bit of a ravine with a creek going through it. No one uses it because they would be in the water and no one can see in it cause it's a ravine. Well, I decided one day that a little water would be OK, so now I always just plunge into that knee deep freezing creek and am able to get right behind the enemy base and cause some havoc. The overall idea here is that the most un-comfortable route is never guarded.
It's not your marker that makes you a great player, it's how dumb the other team is.
