Ireland have mastered Death Zone rugby and there are many people who have helped create the conditions for this sporting triumph.

Ireland's superior pool of players and coaching staff, including two RFU rejects and experienced backroom personnel, have provided them with a consistent selection that will enable them to secure the win against England.

The longer Scotland keep the game close, the more confident they will become as they look to take advantage of Ireland's poorer second half performances.

When the ball is in play, a rugby referee has 138 potential penalties he may award, a staggering amount to assess while keeping up with elite professional athletes.

The lineout will be a key battle in the tactical war at the Aviva. Ireland will have a plan to restrict France's attacking ambitions.

Coaches would typically be replaced due to poor performance in the first part of the cycle, but it is very unusual to be let go within 10 months of the biggest competition as in the cases of Eddie Jones and Wayne Pivac. 

Rugby unions all over the world are facing increased pressure to address the concussion problem in the game.
