Every young rider who gets a pro contract has at some point had a good result & showed promise. It's why they turn pro.You clearly don't know much about Vingegaards history. On his old team ColoQuick they tested him back in 2016 and it was clear he was a complete physical freak. They talked about him as a potential winner of the Tour even back then. This is three years before he even joined Jumbo. At 20 he broke his femur, and his development was set back probably at least a year.
This notion that he came out of absolutely no where is just plain wrong. Clearly he burst onto the scene quite suddenly, but he was seen as a climbing prodigy, even in his teenage years.
But making that jump to greatest GT rider in the world (capable of smashing ITT's, short climbs & long climbs) over 18 months, i.e. going from bottle carrier filtering breakaways in November 2020 in the Vuelta to the rider we see in this TdF today? No.
But you can't ignore the radically different professional environment at Jumbo, i.e. 2017 Jumbo is not 2021 Jumbo.It was far more sudden. Rogla was a completely different climber in the 2017 Tour compared to the 2016 Giro. That was a bigger difference than that of Vingegaard from the 2020 Vuelta to the 2021 Tour.
With your own standard, you might as well call that a Froome-like transformation. But that too would be a poor comparison.
Vingegaard came after & benefitted from an existing structure which Roglic didn't have. Maassen also described Roglic as a 'Ferrari' when they signed him but it took years of ironing out all the kinks to get him into shape as a race winner, along with building a team around him.
There's no comparison between the trajectory Roglic took towards the top & Vingegaard. Where are Vingegaard's race wins? His stage race wins? Where's anything to show he'd turn into the beast he is today?It was deliberately chosen to be an equally bad example as the one Rackham was giving
It's not relatable or believable. He's dominating the hardest race in the world. I mean people need to square with the weirdness of this transformation & not rehash the same old trite excuses for unlikely miracles again, again & again.
