Not sure that bit of rain at the end was ever gonna make an impact.Yes Pogacar usually likes the wet conditions.
Last year in the Vuelta there were also moments when he had to pass, even in the rain iirc, but the race never exploded right after like it did today. That was the main reason why i have been cautious with his chances for the TDF. But on the other hand, he finished strong in the Vuelta so i'm not writing him off. I have no idea if this was expected for him and his trainers. He can't afford too many moments like these though, one weak moment in the TDF this year (with this many potential top 10 riders), could mean dropping quite a few spots in GC. On the other hand, if he improves again towards the end, he might surprise some rivals again. It would certainly help keeping a low profile.
