I'm not too interested in the nuances who's more obvious, it's clear they're 1/2 in whatever order you prefer. I don't see the rise to the top in cycling as something that special because unlike football the skill requirements are not that important, vo2max, muscle fiber, hematocrit and plenty of other biological are the main factors. As long as you did any sort of ultra endurance sport growing up (and Vingegaard did cycle since forever, just wasn't on the pro teams radar) you might make the jump pretty easily.
At least the Skeletor is kind of specialised on his climbing ridiculousness which kinda makes sense given his 55kg. Pogacar is literally doing everything except for winning bunch sprints but then also puts 5 minutes into super specialised pure climbers like Rodriguez. But hey ho, super talent alert, can do it all, yadayada.
