The spark Ireland needed from the fresh faces earned Sexton shots at goal: One from long-range fell under the crossbar but the next one went over, and Ireland had the lead for good, though not with any confidence until McGrath scored. There was no chance that this Irish team would lose Argentina, surely not.
"We knew Argentina would be physical, they would make it very hard for us, they would be good at the breakdown and good at the setpiece". World Cup semi-finalists in 2015, Argentina have won only six...
"Robbie, I'd be hopeful he will be ok but we have to just wait and see".
"Yes, where we are right now, it will tell us a lot and I think regardless of what happens in the next 10 days, everything is a benchmark", Schmidt said.
With the autumn series gearing up towards a mouthwatering tie against New Zealand a week from Saturday there is a fear that complacency could creep into the Irish camp just like it seemingly did in 2015.
"They have a great record in the Aviva as well. We had to dig really deep", man-of-the-match James Ryan afterwards. "It's great because our one Achilles heel is that we go narrow and they will exploit that if we go narrow", O'Driscoll explains.
"I think Joe really feels as though Argentina are still a bogey team for us, he's still scarred from that World Cup quarter final".
"He was a smart player and a good manager of people", said Schmidt who was assistant coach at French side Clermont when Ledesma was on the playing staff "He has already done an incredible job in broadening his experience for example with the Wallabies (when he was forwards' coach)".
They can undo more of the mystery around Argentina and further erode the aura of invincibility around the All Blacks as two more steps in building towards Japan. So yeah I think it's a really strong team.
"Don't get me wrong they've talked about the All-Blacks already in November camp when they got together for the United States of America week and they went away and those ten players stayed around that are going to be largely involved in that All-Black game".
"The Argentines would probably be, to a degree, a little bit more combative at the ruck than some of the other teams who tend to let a fair few rucks go and then suddenly they'll have a crack and turn you over".
