With two Six Nations campaigns around the corner, a World Cup on the horizon, and the ever present Champions Cup, it could be a defining year for a whole host of Irish rugby players.
We have take a look at five men - each at different stages of their careers and playing at different levels - who have something to prove this year.
Tom Farrell - The Forgotten Man
A few seasons back, Farrell looked destined for a few Irish caps, before injuries curtailed his international dreams.
To break into the Irish midfield, with its world class depth, one has to truly stand out. When fit and on form, Farrell's multi-faceted attacking game has the potential to break into conversations for Ireland, should injuries strike down any of Andy Farrell's main boys.
This season has seen the Dubliner manage a run of games in the Connacht midfield, and if this upward curve continues, international appearances - post World Cup - if even for the 'A' side, may be a realistic goal once more.
Harry Byrne - The Fallen Prodigy
There was a time not so long ago when it seemed as if Byrne had been anointed, not just by the fans, but by Andy Farrell as well, as Johnny Sexton's successor.
He is now, at best, fifth choice in the pecking order and struggling for Leinster game time. This is, of course, not helped by his luck with injuries.
Having begun his Leinster career with such aplomb, he has failed to take the most recent chances he has been given. A trip to the World Cup is looking vastly unlikely, but post-France the 23-year-old will be pining to get back into international consideration.
Caelan Doris - The Elite Performer
The Leinster back rower will be looking to propel himself into the echelons which are often frequented by no. 8s such as Ardie Savea, Gregory Aldritt, Duane Vermeulen, and Toby Faletau.
The 2021 Player of The Autumn Nations is arguably already as good as those aforementioned titans, but his name does not yet command the same reverence throughout the world.
What better time than a World Cup year to prove without doubt that you deserve to me grouped among the world's best.
Rónán Kelleher - The Man Making Up For Lost Time
Up until the recent November internationals, there was still a fair argument that a fit Kelleher should start for Ireland and Leinster, given his specific qualities in the tight.
However, Dan Sheehan cemented his stature as the no. 1 hooker in the nation with superb showings against South Africa and Australia, backing what was a sensational Summer tour.
Kelleher will be given the opportunities to stake his claim ahead of the World Cup, but it will take a momentous effort to take them.
Ruadhán Quinn - The Young Groundbreaker
Munster's youngest ever player, playing in one of the most physically demanding positions on the park, and looking every part the professional back rower for his province.
In his two caps earlier in the season he was taking names on the field, so when he runs out for the U20s in the upcoming Six Nations, a lot will be expected of him at that level.
One of the great joys of being an Irish rugby fan is seeing a young man make his bones for the U20s, and hopefully Quinn will live up to the hype and more.
