I agree but race lenght takes a tool on him. I'm saying this believing he doesn't race classics because he knows he can't maintain his power after 6 hours. But like you said, this hypothesis is not proved.
Not ready to call him the second Rogla in this regard yet. It seems Rogla has a problem with that in monuments, yes. Nonetheless he managed to win a monument (had luck but he was up there fighting) so time will tell how it goes with Vingo.
