I think the gaps for the other riders speaks for himself. You are starting from the assumption that they never faced each other, but i don't think it’s so necessary to know who can be the most stronger by facing each other.So long story short: Vingegaard and Roglic never competed while both at 100%, and Pog and Roglic competed once. That’s why I’m saying your claims are assumptions. Which is ok, by the way. It’s just that I don’t agree with most of them. I agree he is worse bike handler (but at least as good descender) and that he has problem with very long stages (which there are none at this year’s Tour). He might be a better TTer on average, has a better sprint, better 5-8 minutes average output and maybe (not sure about that) similar long climb power output.
Considering those assumptions: if he stays on his bike and reaches his best-possible FTP, he might have a chance against 100% Pog/Vinge.
If Vingegaard keeps repeating last years TdF TT performance, I doubt anyone has much chance anyway…
We can compare physically the perfomances between them in Grand Tours at 100% (the TT you talk about is an example), but like i said most of all, the gaps to the other riders, and then we compare the gap between Roglic to the others riders when he was at 100% during Grand Tours.
In my opinion Vingegaard and Pogacar are in a league of his own, when we look at the gaps between them and the others in mountain stages. They can easily put 2/3 minutes on the others riders day after day in the mountains, with an ease that we don't see in others riders. Unless Roglic suddenly shows power that he never showed in his career, i don't think he is able to follow them.
