Tour-Vuelta by far the two biggest races on the calendar for Movistar and Mas has shown the ability to consistently peak for both races. He has shown this spring and last Vuelta has he has taken another step and is a legitimately potential Vuelta-winner and a top3/top5 rider in the Tour. If anything, I think his Vuelta-chances decreases when not riding the Tour as it seems he has been better in both Vueltas compared to the Tour so far, so I cannot see how you'd change the schedule up - especially considering the rest of the roster as well.
