Build that wall?!

I coach soccer. There is a term for when players stand in a line to prevent a good view of the goal and potentially block the kick. It's called a wall.

So we're playing today and the opposing coach tells his team to build a wall on a free kick. They do. My team cleverly passed the ball to a player near the end of that line and then that player took a shot on the goal and scored.

The opposing coach said something about the wall not moving.

And that's when the metaphor hit me: it's always possible to get around said wall.
