Princeton has adapted box lacrosse into their offense in a more then most.

They do this by using 3 groups of 2 out of the open set.  We used to teach clearing out of the way for the man with the ball.  This uses much more of a pick, re-pick and then pick again philosophy.

If you watch the video you can also see that the men off ball are working to get each other open.  This would really make the slides very difficult.
