He was in Denmark in a slow team, doing a part time. 2019 was the first year at Visma.Sure, but supposedly, it's this unique ability to quickly improve that makes it possible that Vingegaard might be able to be a TdF contender despite his injuries. That's why the coach mentions it.
All this natural ability/genetics always makes me wonder where Vingegaard was before his 2020/21 transformation. I remember him saying it was impossible for anyone to follow Roglic in training. That Roglic was some sort of once-in-a-generation phenomenon.
Fast forward a few years ...
He improved faster at Visma, despite some issues with covid and some injuries in the tendons, and psychological issues.
