A month after the humiliation at Twickenham and the worry which followed about the first hurdle of the World Cup against Scotland, Ireland cleared it easily on Sunday morning.
Joe Schmidt's side dominated the Scots in Yokohama, winning 27-3.
"Rory Best has every reason to be pleased with that performance," said Brian O'Driscoll on ITV's coverage of the game.
He was probably trying to temper excitement at home and within his own squad [in his post-match interview] - yes, there will be lots to improve on.
That first half performance, all the damage was done then. When the weather conditions came down in that second half, 16 points seemed like a huge lead.
They didn't have to do a huge amount. They knew Scotland had to do all the playing, had to chase a lead. They played simple, concise rugby, good kick contests, and got their bonus-point try out of that. It was just a good, all-round, solid performance.
There will be some nervous guys who have been out through injury - will they get back in for the next one?
O'Driscoll's fellow former Ireland captain Paul O'Connell was also in the ITV studio.
"Scotland were really poor," said O'Connell.
"Ireland were utterly dominant. The last thing Scotland wanted to see at half-time was that rain. It's very difficult to chase a game in those conditions, especially with Ireland's line speed.
"Scotland had a crack at a five-metre drive, they lost it. Ireland hoovered them off a ball in a scrum on Scotland's own put in. Ireland were excellent but Scotland were really poor in the first half and even succumbed even more in the second half."
