Ireland begin their Six Nations campaign this year with an unusual sense of the unknown. Andy Farrell, of course, is on a Lions’ sabbatical and Simon Easterby is therefore thrust into the limelight.

On the face of it, the change doesn’t make much different as Easterby’s been a central figure for over a decade as assistant Ireland coach. However, the top job is different and the former Scarlets’ man’s promotion presents welcome opportunities to freshen things up.

A less visible presence than Farrell, Simon is nevertheless respected immensely within the Irish squad. Easterby marshals the Irish defence expertly and is no slouch with lineouts, either.

Farrell’s voluntary absence affords the opportunity to experiment and tinker a little with this exciting squad. Ireland’s attack’s been lethargic of late and needs not just new ideas but different ones. Easterby, and new attack coach Andrew Goodman, must make their mark in that regard.

It’s early days, but Easterby’s demeanour has impressed so far. He seems relaxed and chilled in the role. Nothing fazes him. That’ll be tested over the next few weeks, but the initial signs are very positive.

Above all, this Six Nations’ window allows a reset, a chance to build on the wonderful foundations laid by Farrell over the last six years. New voices always add originality and novelty, after all.

Simon’s just keeping the head coach seat warm, of course, and the brilliant Farrell will return. But this Six Nations is an excellent opportunity for one of Ireland’s most underrated assets. Easterby’s mission is to show the world Ireland’s envied strength in depth extends beyond its player pool.
