Hager was ambivalent when assessing the impact of the new crop of talent.
"[The series] gave me a good look at our next generation of hockey players and gave the young ones a chance to learn what it's like in our environment," the coach said.
"At this stage, the group is inconsistent in how they play. Some days they're good, some days they're not so good. That's what they've got to learn now."
Finishing their chances was one area in need of improvement as, aside from Saturday's 5-2 victory, too many opportunities were squandered against Malaysia.
February's trip to Argentina will be when those improvements can be put into action, and with the squad now given the summer off, Hager was left to look back on a 2016 that was pleasing in many aspects but missing the prize that mattered the most.
"We had some good results throughout the year," he said.
"Our own expectations and our own goals were to win a medal [at the Olympics], and we didn't achieve that. So if you look at it from that point of view, we failed for the year.
"But we won a couple of tournaments, we found some new players in our system, so it's been pleasing but disappointing at the same time."
