One-Directional Soccer

Occasionally, in gym class, we play soccer. If Pélé were watching, he'd probably croak and die. Why? This is crappy soccer. Soccer from Hell. Sloppy defence, offensive people that stay in the offensive zone waiting for the ball (i.e. loafers), 4 players a side, 3 on the defensive end. Plus, if they know that the ballhandler has a moster kick, they clear the way for an easy goal. You'd swear you were playing "Pong", not soccer. There is only one way to fix this. One-Directional Soccer.

One net only. 2 goalies in that one net, one per team. 4 players per team are running with the ball. You can only pass and move forward. If you drop backwards of pass back more than 5 feet, your carded. The field for this unique brand of soccer wold have to be as long as anormal soccer field, but much more narrow. And, if possible, a motorized trip wire that follws the players while running. That way, if a player falls behind he is carded. If the ball falls behind the trip wire, the play is dead and the wire stops. Then, they start from wherever the trip wire is. I would make it 5 cards before the ejection (instead of 2 yellows or a red). Once a guy scores, the players go back to the starting line and the process repeats itself for 90 minutes. There is only one shot taken, though.
