Winning stages at the Tour and finishing 2nd is no small feat. He already has two overall wins to fall back on, as well. It is not the end of the world for him if he loses here, I am assuming.Indeed, Pog relied on his explosivity to gain some seconds back on Vingo, but at an extremely high cost. He indepted himself and, when Vingo brought the check at the TT, with a sardonic smile, Pog had no cash left to pay the bill. Vingegaard simply has more stamina, a bigger engine for the third week. And it was a massacre.
With that said, he should probably take a year off from going to the Tour if he can unless other parties puts the pressure on that he has to go there. He should try to win the Giro now, while he still can next season.
