So basically, Movistar have a great support structure in place as long as there is a clear leader in place, and when they have too many stars they aren't able to manage them in the manner of a USPS or a Sky without upsetting somebody? I mean, that's how they've been since time immemorial, remember Olano and Chava in '98?
Landa is a lot more philosophical and realistic about the team. To run the multiple leader set-up they committed to with Valverde/Quintana/Landa resulted in them having to tie a lot more of the budget into leadership, offering less support in terms of both race entry spots and simply the quality of domestiques as they had to sacrifice renewals of a lot of useful ATVs and rouleurs to afford it.
Of those who've left with grievances, you can see reasons for a lot of it. Carapaz had just reached the point of being able to lead and his agent was on bad terms with the team. The team backed him to that Giro win and then probably acted like he owed them more than he did or got pissed at him because of Acquadro. Quintana, like Visconti before him, was seeing his results diminish and not enough room in races for specifically his support guys, and was probably being marginalised somewhat in the multi-leader setup, certainly more than he had been in previous years such as 2014 and 2016 where Valverde had initially worked for him. And López, well, precocious but temperamental, short-fused rider known for anger outbursts signs as co-leader for team that he has previously publicly slated, which is renowned for questionable tactics and history of struggling to manage multiple leaders, what could possibly go wrong? Why do you think a guy at 26 and coming off winning the queen stage of the Tour de France only signed on a one-year flyer? The thing that was weird was simply that the experiment had worked... almost too well. The team had backed him and given him time to recover from his case of Covid, he'd been a good servant at the Tour and whatever the off-bike stuff was like, on-bike he was complimenting Mas well in the Vuelta. He'd signed an extension because the experiment had been deemed a success. But a guy as volatile as Supermán working with a guy as stubborn as Unzué, there was always the possibility of a blow-up, I just didn't expect it to be quite the way it happened, or so soon after the extension. I thought it would either be immediately and early on, or once he'd extended, some simmering tension across next year until it all blew up. Not "everything is fine" one minute and "rip everything up and salt the earth" the next.
