Saw GE do this today. Liked the simplicity and the pace.
I’ve done a variation of this, I think with a circle and with more players (and maybe as keeper practice), but I like how this isolates the defender and forces the defender to move and think.
If you have one (or two) big goals (I’m assuming I won’t have four big goals), you could restrict the shooting, i.e. after two small-goal-shots, you have to shoot at the big goal with a goalie.
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.
