The forwards, the runners…

In 3v3 soccer, the forwards have to run. If you have players that don't want to run, then your team will never get to the next level. Especially if a player loses the ball, they have to run back on defense as fast as they can. If they see that they are completely beaten and cannot catch up to the opponent with the ball, they need to run back and block the passing lanes. Remember, once they are beaten, your back player will try to slow the fast break. To be honest, that is what separates the really good teams from the bad teams. Bad teams quit, and rarely come back to help, but the good teams always swarm back and make it very difficult to score.
