By changing running angles, centres can leave gaps for wingers. Use ’ins’ and ’outs’ to create gaps and release the blindside winger.
The terms ’ins’ and ’outs’ are also known as ’unders’ and ’overs’.
They refer to the running line of a potential receiver. This is, for example, when the inside centre (12) runs out and then in, or vice versa, to open a hole in the defence.
An in (or under) is an out-to-in run, while an out (or over) is an in-to-out run.
On their own, these changes of direction can be a very effective way of exploiting space.
Defenders have to move laterally to cover the attackers, potentially unbalancing them before attempting the tackle.
When combined with a set move with the blindside winger following a scrum, these can be a lethal attacking weapon.
Set up your backs as shown in the illustration below - they are in the blue shirts. Your blindside winger (11) should be standing behind the 12.
The opposition is not able to move its own 11 across, because this would leave the white blindside undefended at the scrum and at the mercy of a pick-and-go down that channel by the 8.
The fly-half (blue 10) runs forward to draw their defender after securing the ball from the scrum-half (blue 9).
The blue 12 runs the line for an ’in’ ball while, just behind them, the 11 runs an ’out’ line. The 10 can then pass the ball to either of the two.
This has created a 2v1 situation against the white 12. If the blues now break through and carry on supporting each other, they will have a similar 2v1 against the white full-back.
If the 11 is quick enough, they don’t need to start near the 12, but should wait until they go into the scrum before wandering around into position. The 12 and 13 should maintain a good spacing to keep the opposition defence fairly spread.
