For Pogi maybe. Not necessarily to an outsider looking objectively. That ugly sister GT was still important to riders of Contador and Froome's calibre.
He came 2nd to MVDP last year with a crash. But what if he never wins P-R and ends his career with no Vuelta victory? To me you can't be sad about missing a long shot. Missing the easy win when you had the chance isn't good either.
In not winning all three GTs he would finish his career with an inferior record in that regard to riders like Contador, Nibali and Froome. And I don't think anyone would say those guys are on the same planet.
Why is it not possible to win the Vuelta first then tick off P-R once that box is ticked?
p.s. - I am still undecided on this after reading the replies from yourself, Salvarani and James.
But Contador and Froome where never winning monuments or worlds. They were "only" GC-riders and in a different era.
What about the Evans WC? How does that stack up objectively... would you take it away for him winning a Vuelta instead?
Back to Pog. He rode PR and finished 2nd... keep the momentum. Go there again. He did it once with great success. Try again. Cant really fault the guy if that is what he would just like to do, instead of trying to win the Vuelta right now.
As many pointed out. The Vuelta is just not that important of a race. Especially if you already have 4 Tours and a Giro to your name, when GC is also not the end or be all for ones palmares. Not while still being only, how I would phrase it, 27 and still at your very best. Vuelta will still be there and if he ends up never winning it... then that just what it is.
The Vuelta is right now tough to schedule. The downside would be him not racing the cobbles and doing Tour-Vuelta instead... but that could also mean he would be too tired in Worlds + Lombardia. Just look at Vinge after this Vuelta.
So skip Vuelta...
To maximize his own chances to be able to target Flanders, PR, Worlds and Lombardia instead of it... is this even a choice?
Of course, it is skip Vuelta for now.
Im sure he would like to be able to retire one day... having won all three GTs, but give it time.
Im also sure he would like to win MSR and PR, while MVDP is still there. It would be deserved and a great achievement if he beats him. Just like he did in Flanders. I want to see more great battles between them.
And as I said in another post, I just think he does not find the GTs and everything around it very fun. So if he doesnt have to do two GTs, for the time being, and "only" Tour + all the monuments... thats is what he would like to do. Especially, when worlds is on a course that suits him. Like this year.
It will also be harder to win MSR and PR later imo. Try to win them while you are hot.
And as someone else said, when Vuelta might make more sense in a couple of seasons to target... he will ride it again.
But the future is hard to predict. Who really knows. Take nothing for granted, which goes for any race on this list being discussed. For any of these riders. They have all achieved quite a lot.
