I would progress this where, initially time is given for the team’s to switch and then the switching has to be done on the fly.
Just thought of this one myself. We had some issues getting out of the back quickly enough, and I was looking at various transition games. This isn’t quite transition but might make a good first step. (And I forgot to add the ball to the illustration.)
I might want to include a crease in front of the goals; I can see the defenders, especially if their not live-defending, just parking themselves in front of goal, but otherwise I like it.
