It's been the story for much of their involvement in first-tier rugby, but again on Saturday, Argentina exposed the absence of clinical finishing that has shown up before in their play.
It's one of the main factors that's prevented the side from being able to claim a Rugby Championship victory in 13 attempts now, and although the weather in South Africa certainly didn't help, cooler heads are needed in high-pressure circumstances.
For ingenuity and off-the-cuff running, the Pumas are often among the most inspiring sides to watch, their backs possessing the ability to create something-from-nothing opportunities almost at will against lesser opponents.
However, the likes of Manuel Montero and Horacio Agulla won't see their try counts rise against the Rugby Championship big guns until the finishing touches are evident, something they certainly have the potential for if club form is any indicator.
Against such strong opposition, it's obvious that ventures into enemy territory will be fewer in number, and on Saturday, the Pumas made errors in six of their seven trips into the South African 22.
The most agonising moment came in the 75th minute when a pick-and-drive tactic was quickly disassembled by the Springboks defence, a score that, if converted, would have tied the scores at 13-13.
If Hourcade's men are ever to subvert the minnow stereotype they've developed among the Southern Hemisphere's giants, this remains a key aspect in need of addressing as far as this weekend's loss is concerned.
