This is a lineout. It's how the ball is put back into play after it goes out of bounds. Shawn is in this picture. I'm not sure if you'll be able to see him, but his back is to the camera. He's wearing number 3, and he's helping to lift the guy in the white jersey.
And finally, this is just a shot of regular play. One of Shawn's teammates has the ball.
As I mentioned before, I did attempt to use the video function to record a little bit of the game, but it's hard to really get a good view of what's going on, especially when they're on the other side of the pitch. But here's the best video that I was able to come up with from last Saturday.
