Editor Dan Cottrell adds further context to two sessions.
A ’soft edge’ is a place in the defensive line where there are opportunities for a ball carrier to go through.
Whoever coined the phrase might not have realised what a clever term they came up with.
An edge recognises that an object has come to a finish, like the edge of a cliff or wall.
That means there is something to fall over (bad news, obviously) – or, in the case of attacking opportunities, a potential space to go through.
There are two main edges in a defence. The first is next to the ball source, either at the set piece or breakdown. The second is at the end of the defensive line, where the winger is normally stationed.
Rucks can have soft edges. Quick-thinking scrum-halves look to exploit even the smallest of holes to dart through.
Most teams will work hard to make this ruck edge seamless. In other words, a defender will stand so close to the ruck that there’s no way through.
To create a soft edge at the ruck, the attack has to create very quick ball.
However, plenty of teams fail to capitalise because they wait for the 9 to come in to pass the ball away.
Why not have a forward pick up and go themselves? If that happens a couple of times, the defence soon swarms around the ruck, which inevitably creates spaces elsewhere.
The second edge, the one where the winger stands, is harder to exploit.
That’s because attacking teams are often faced with four or more defenders. And how often have you seen a 5v4 or even a 7v4 work?
It can work, though, if your players run scary lines and the passing is slick enough for it.
The reason why the word ’soft’ is useful is because, often, the edge is only temporary. A gap is soon closed if the defence has time. That’s why players must recognise the edge quickly and attack it.
It’s a combination of well-executed skills and decision-making. I’ve used this session by New Zealand assistant coach Jason Holland a number of times to improve players’ recognition of soft edges.
I don’t expect them to succeed every time. In fact, your ratio might be one in every five attempts – in other words, every time there is an overlap in the activity, your team doesn’t score on four occasions, but does on the fifth.
If that happened in a match, you’d be pretty pleased with that.
Why? Because they have to identify the overlap, move the ball to that side of the ruck, execute the skills accurately and hope the defence doesn’t cover across in time.
A while ago, I challenged our grassroots coach writers with the problems of young players and their contact skills.
How many times have we seen these players go into a tackle and lose the ball?
Sometimes, it’s simply a mismatch of relative strengths. But, most of the time, even with a mismatch, a player can manage the ball better and not have it ripped away or just become stuck in a maul.
These skills are just as relevant for senior players as junior ones.
So, when Ian Diddams came up with this exercise, I used it as a breakout session for my more experienced teams.
It replicates two occasions when the ball carrier meets a defender. The first is when they step away from them; the second is when they step in.
Because the exercise works on both in a short space of time, it has enough variability to make the ball carrier come up with different solutions.
You can set this up in several ways. I prefer a practical area on the side of a training game, where four to six players are moved out of that game to work on the skills.
That means, with a squad of 15-20, 10-14 are playing in a game, and the rest are working on this skill for three to four minutes.
I tend to have one box per group of four or five; that might mean four boxes for a large group. The defender keeps swapping after every two players have gone through the box.
Don’t spend more than five minutes on this exercise. It’s a good one to come back to, or use as part of a rotation of skills exercises.
Also, think about taking away the cones after a while, so the players are not looking down before they change their lines of running.
