Yeah as others have said, clearly it was nuanced. Roglic and Vingegaard both rode selfishly at times, but the both also ultimately delivered Kuss the win when most can agree that either could have beaten Kuss if truly raced head to head.
One thing that gets lost is Roglic was riding to tie the record for most Vuelta wins and was in pole position to do so before teams let Kuss get up front, thinking he wasn’t a threat, and the team set Vingegaard up to jump past Roglic (heavily aided by the competitors just inanely letting him ride away without even the faintest attempt to control the damage). Plus, Roglic, as many like to point out, is 34 so his opportunities are theoretically much more limited than Kuss and Vingegaard’s. Plus Vinge had already claimed the much bigger Tour prize, which Roglic was not allowed to ride. All reasons why Roglic should have really wanted this win and to be supported in it. All the Americans going off about how the team owes it to Kuss or full of ***, and I’m American. Kuss is paid to be a lieutenant.
But all in all, I don’t think there is a villain here, just competing interests between captains where only one can win. Roglic had to go to Bora to avoid that, but there’s a good reason Jumbo “chose” Vingegaard and it will be very tough for anyone to beat him.
