Drill to practice team shapes or backs moves against a defence with less numbers than the attack.
Set up a "ruck" with a scrum half/feeder, 3 defenders on the back foot of the "ruck" and 4 attackers opposite them. The attackers attack the defence, then turn round and attack back the way they have just come.
