Vingegaard is quite aggressive with positioning in the bunch for what it's worth. He's always on the front at the end of sprint stages & has no real fear on descents. We'll see whether that changes after Itzulia when he eventually comes back.
Won't exactly be the first time in history, where daredevils transform into scarecrows, whereafter things go completely wrong for them on especially technical descents where confidence and a relaxed body are crucial essentials, while a stiff body and nervous handling result in a negative spiral as a consequence.
It takes a very special mindset to pretend like nothing happened and just keep flying down, right on the edge, like Jonas has done on several occasions up to Itzulia crash.
Regarding the Massacre in Combloux, maybe I'm not so much into an Apology of Socrates, however
comparisons to justifications have been made.
In addition, I studied Pogi's riding style on the two previous alpine stages, despite him challenging Jonas on several occasions, my impression was that signs of fatigue were beginning to appear heading into the 3rd week (completely logical with Pogi's far from optimal preparations).
This conpared to a much Le Tour prepared Jonas who ½ year in advance mentioned that stages 16+17 would be the ones deciding the Tour, added by a final reconnaissance of the route on the rest day with close reading, while a pool boy just enjoyed life.
It takes quite a bit to discard it all...
(maybe with the aim of putting on the comfortable easy hat of no)
That said, I think - even with marginal gains diet and training optimizations - that the improvements we have witnessed over recent years are really startling, so I maintain my healthy skepticism, quite generally.
Just my 2 cents.
