Sean kelly is the same guy that yesterday talked the "bullsh**" of too much vertical meters in today's Tour de france era, that can lead to "clinical issues", maybe you are inspired by the bullsh** he says.
Pogacar's coach and pogacar's general manager already said that pogacar doing the classics is not a problem for is shape at the tour, it's the opposite. So, i think they know better about that issue, than you.
Another point, pogacar already said this week that he could never beat Vingegaard on that TT at the Tour de france, so now he is contradicting himself.
Pogacar did the best numbers of his life except for the La loze stage, pogacar's coach already said he was in great shape in the first 2 weeks, so there's no indications that he wasn't at his best in the Tour, except for La loze stage, but he could never win the Tour on that stage, after what happened in the TT.
The best riders like to protect themselves when they lose, and they always speak about some "excuses" to justify they're defeats. It's not just pogacar.
