Duncan Casey: The luck of the Irish draw cannot be overstated. Now they must capitalise

If you look at the profile of sides that Irish teams have traditionally struggled against in recent years, it’s the behemoths. The giants. Ireland may win by 3-5 points but in all likelihood will pay a physical price for doing so.

Truth be told, I was a bit disappointed with what Tonga offered against Ireland. Having benefited more than any other side from the shift in World Rugby’s eligibility rules two years ago, there was much excitement about what Ikale Tahi might bring to this year’s tournament. Boosted by the addition of an assortment of All Blacks, as well as Super Rugby, Top 14, Champions Cup and URC winners, there was more than enough talent in Tonga’s starting XV to give Ireland cause for concern.

While Ireland impressed by clinically disposing of their opponents, they did so without having to get out of third gear. There were some moments of magic from Salesi Piutau which drew gasps and applause from the crowd in Nantes but there was little else to challenge a cold, calculated and ruthless Irish side.
