@The-Irishman ABs weren’t tested in 2015 after the first Argentina pool game. Worked out ok 
Yes, 2015 team were much better than 2023 vintage, but just pointing out that a lack of tough pool matches doesn’t always mean you aren’t prepared for the knockout stages.
Ireland will be playing their third big game in 4 weeks. It takes a fair amount of energy to maintain peak performance and mental edge. Just to counter the strong pool argument.
At the end of the day, we don’t know who has been best served by their respective pools. The battle hardened, potentially less fresh Irish or the battle light, potentially more fresh ABs? Roll on Saturday.
