Sure, but, as long as Ineos and Jumbo have several riders still in the top GC game, they can selectively send them up the road early, now one, now another, like a multi-front attack, and UAE can't possibly cover all the moves. If UAE were strong enough, like the Sky of yesteryear, then they just set a high enough tempo and good night. But I fear they are not and this could be Pog's only real danger, his Achille's heal if the other teams coordinate properly, in theory anyway. In practice, though, perhaps it's like you say. At any rate, could be interesting to see how things tactically develope from here on out in this Tour.I don't think that is a "problem", just a concern. Pog and UAE just need to be wary.
As for team strengths, both Ineos and Jumbo can have a stronger teams but it comes back to how strong is the leader relative to the competition. Two examples that come to mind are Ineos 2022 Giro and Jumbo in 2020 TdF. Very strong teams but in the end the leaders were the difference.
Looking at their leaders, Vingegaard obviously looks closest to Pog after today, Thomas I think is just hanging on as best he can and seems to be aiming for a podium. Poor Roglic will likely lose too much time before he finds his legs which I hope he does.
On the other hand, UAE had to work quite hard yesterday (was it wise, as has been pondered?) and barely, just barely had the reserves to set up Pogi for the win and even he just bettered Vingegaard in the end (demonstrating the Dane has upped his game and likely won't be dropped in the Alpes by the Slovenian this year). Now, what if Jumbo sends Roglic on the attack with Van Aert on the Galibier, with Yates or Martinez or even Pidcock in the move? UAE will have to burn matches to contain it or real it back in entirely by Colle di Granon or Alpe d'Huez depending on the day, at which point Pog is either on his own or with just one helper on Granon or the Alpe. And if he has just a so-so day and Vingegaard is flying and/or Thomas is going well? Could be trouble. Of course, Pog could be prodigious again and dominate his rivals. But, to repeat, things might not be as straightforward as they have appeared thus far.
