The Outback Full Back
With kicking being such a feature of the modern game, the positioning of your full back in defence can be critical.
In the past, the full back would stand as far back as the distance one would expect from a regular kick. However, nowadays the ball is being landed on wingers more frequently, so there is more than one reason for the number 15 to lie even further back - to catch, cover and support.
As an occasional full back myself, I think that setting your full backs deeper, into the "outback", gives you a number of advantages.
Advantages of depth
An improved running angle: This aids speed. The deeper full back will arrive at greater pace on to the ball or to support a winger fielding a kick, and with a choice of angles to take.
Improved vision: The full back can see where the gaps are or are going to appear. A full back who receives a pass from the winger can also decide whether to run or kick.
Simpler catching: It is easier to catch a high ball or take a pass when coming forwards, rather than going backwards.
How deep?
If the field is split into four, using the 22m and halfway lines, then there should be at least one quarter space spare between the set piece, ruck or maul and the full back. The depth can be then adjusted according to the opposition and the weather conditions.
How wide?
"Follow the line of the ball" is the adage I was taught, with the full back tracking across in line with the ball. The more sophisticated full back will stay within the confines of the two 15 metre lines and will try to read the actions of opposition fly half.
Standing where?
Here's my top tip for full backs expecting a kick. Watch the opposition number 10's shoulders. Where they point is generally the direction in which the kick will go.
