When Ireland plays against the All Blacks, it will be a busy day at the office next Saturday.
Joe Schmidt's notorious video review session will prove grim to many of the squad on Monday morning.
Ireland's line-up worked poorly at crucial times as Rory Best and Iain Henderson went down before the hour, while Sean O'Brien and Kieran Marmion left the field with worrisome injuries. James Ryan, however, was outstanding again.

Schmidt warned this week that all players looking too far into New Zealand would be in the stands in seven days. Regarding this evidence, there will be changes for the visit of Steve Hansen's men.
This was a stuttering and faulty performance interrupted by unconstrained errors and untypical indiscipline.
In all of Ireland's attempts to attack, they struggled to tear down a determined Pumas outfit, brilliantly guided by their captain Pablo Matera on the Blindside flank, adeptly assisted by the imposing Locker Tomas Lavanini.
The Irish scrum proved the difference to Marmion and his successor Luke McGrath, both slipping off the big drives, while Bundee Aki, arguably Ireland's best at night, made his way for another and was sufficient against the determined visitors.
Argentina has made great progress and contributed a lot to the competition. The selection of Guido Petti on the flank proved to be inspiring, as he wreaked havoc on lineout times. Their talented threesome of Emiliano Boffelli, Bautista Delguy and Ramiro Moyano struggled intentionally all night while young midfielder Matias Orlando made a real discovery.

There was an early drama when Robbie Henshaw wound in the warmup with a thigh injury and Will Addison, who was not named in matchday one, made his first test start.
The Cumbrian-born midfielder who qualifies for Ireland through his Enniskillen-born mother arrived from Sale Sharks in Ulster last summer and made a big impact.
The 26-year-old sat in the stands with these parents when Pumas grumbled at the 2015 Cardiff World Championship. Three years later he ran out on Lansdowne Road.
He got a lot of touch when he presented his boring running style while Ireland stretched out the visitors. It was however, who struck Argentina first, Sanchez stroked a minute minute penalty after Jordan Larmour was isolated on deck.
Ireland then set to work and established a camp in the area of Pumas. After a series of penalties and a stalled line-out drive, the home team were given a first-class attack urge, and Marmion scored the opening attempt as Argentina's pack rolled back at a rate of knots. Sexton has made the conversion addictive, but Ireland was running.

Frustrating, Schmidt's team coughed after the restart, thanks to a brilliant attack by the flying wing Moyano with Sanchez on 6: 5, as Ireland deposed again.
Schmidt will not be satisfied with the high number of errors. Within minutes, Peter O'Mahony hacked a free-kick while Best dropped a lineout.
This is not the accuracy we are used to under the kiwi.
Restarts and the lineout continued to be a problem, and the alarm bells rang as Orlando ran through Sexton and Aki before joining fellow player Jerónimo De La Fuente, who then miraculously outsourced to Delguy. Lavanini and Agustin Creevy gave Briggs the quick hands of Sanchez and Javier Ortega Desio sent Delguy into the corner. His attempt performs it in nine tests.

Argentine head coach Mario Ledesma noted on Friday that the Pumas scrum was not the force he once was. Before Ramiro Herrera and Juan Figallo and the retired Marcos Ayerze, the pumas in Santiago García Botta and Santiago Medrano left two front greenhorns, and they showed their callowness against this seasoned Irish pack when they were pulled off their own ball. From then on, Ireland set up camp on the Pumas Line.
Aki looked through as if he was flawless, but gave off a great goal from the towering Lavanini, but two phases later, the Connacht Center stepped through the cover and rode Matera into the goal.
Sexton's conversion pulled back the lead, but O'Brien looked on as he clasped his arm and Dan Leavy replaced his Leinster team-mate.
Ireland's No. 10 traded sanchez penalties, which should leave it 15-14 before the break. In the changing room there is much to think about for Schmidt and his side.
Ireland would try to improve its stakes, but Argentina had their first two second-half points by another Sanchez penalty as Sexton later sent a far-reaching effort from the posts. He would then pay off with a successful 58th minute.
There was bad news as Marmion hobbled after 56 minutes when Luke McGrath entered the fight. Best and Henderson were soon inspired by Sean Cronin and Devin Toner. Not a good night for the lineout brain. Schmidt had seen enough.
Luke McGrath almost made an immediate impression and sneaked through another dominant crush to demand a much needed attempt.
Sexton's third penalty of the evening sealed victory six minutes from time, but concerns about this patchy display will continue for some time to come.
