This is a 4 v 3 overload drill in favour of the attackers The area is set out, with four attackers spread out across the back line, three defenders 5 yards in front them, and another row of three defenders 5 yards behind them On GO, the coach passes to the first attacking player, and the ball travels along the line to eventually reach the end player That player is then first to reach the next line of defenders, and the ball is passed back along the line and the original attacker should receive the ball in space to 'score a try'.
