Movistar want to use Pedrero and Amador as little as possible here, which makes total sense. They will need rouleurs and ATVs to carry them through a fair amount of mountains if they want to defend the maglia rosa throughout the final week, so controlling a 230km intermediate stage and exhausting Rojas, Sütterlin, Carretero and Más is not going to be in their best interests. They will want Carretero, Más and Amador to help in as many slopes as they possibly can in week 3 as they still need more time on Roglič with another TT to come (see, this is why TT mileage is a good thing for GTs). Cattaneo is 37 minutes down, so why not let the break take this day? Movistar have already got everything they could need out of the Giro - two stage wins and time in the maglia rosa. They've already had a good race; anything else is bonus. There are plenty of others, however, who still need to salvage something from their race and for whom this is a potentially good stage. If the stage win is out of the equation, that's 10" fewer that anybody can gain on Carapaz.
