However against Ireland we saw the side that had given us the Fox defence give us the Flying Squirrel in its final form

Whether this will catch on will be interesting to follow though the use of the leg, does offer a possible chance at improved outcomes

We first saw this in their game against France where under pressure 2 players went for the block rather than the intercept.

This makes sense trying to avoid yellows while disrupt a pass and leave just enough body in front to tackle the opponent.

France showed much the same against Italy

Both sides working hard to set their pod and attacking with width off an edge

Tony Brown has truly changed how the game will look for the next 6 months at least!

Ireland showed it often against England setting the tone from round one

The first example shows how good connection in defence from England pushes them to an edge

But they can't stop Sheehan on the second example

This is a great example of his combination in the Centres for Italy

A well timed line on the outside of 13s shoulder helps him break the line with the wheels to finish.

Notice how his opposite number is forced to double D, allowing Menoncello too weaker shoulder and its try time.

We see Biarritz put all this together for their final try using layers and offloads to complete the come back.

The adjustment on the 1st pod is crucial enabling them to change picture forcing the defence to adapt.

They then stay on top impressively and keep the move flowing with offloads to score.

We see the same here.

Starting with a penalty that is taken quickly they break the oyonnax line.

While it only needs one offload to finish the job notice how close the support runners are and the work of 14 to adjust and make the final pass easy.

One of Biarritz's best weapons was their ability to keep the ball alive. In the clips below we saw their offload game to fruition - with an adventurous chip on the exit kick starting the move for their first try.

Notice that the support runners are flooding ready for the pass not just the ruck.

However Biarritz responded in the second half. Holding out these 2 mauls.

We see the change in Biarritz's 2 pod defence policy and while they give away a penalty at first they look more comfortable.

For the turnover they split Oyonnax's back shift and get on ball. A pivotal point in the game.

One fascinating battle came at maul time.

Oyonnax got away to a strong start, including for their first score.

Part of this was driven by the Biarritz strategey of defending front and middle with two pods. This gave Oyonnax a chance to set a drive relatively unopposed and get go forward early.

Biarritz on the other hand looked to move the ball against the narrow Oyonnax defence.

We see a clear use of layers to achieve this allowing them to pin the inside defence and preserve space on the edge.

Important to underline the work rate to win the race and set before each phase.

In attack we again saw two different strategies.

Perhaps looking to adapt to Biarritz's numbers on feet strategy Oyonnax looked to create short edges before using layers to create dents and half breaks.

Also note the use of the scrum half to add a number for many of these attacks.
