Contador is not the only rider in the race. Astana may sense Sky weakness. If they do, hey should put the hammer down in the last 30km today and try to tire out Porte's team mates for tomorrow. Movistar may spy the chance of mixing it up a bit by having Amador going on the attack in the final to put pressure on Aru, Porte and Contador.
Missing a day's racing, potentially a very important stage near the end of a tough week is silly. Contador might be complete toast, and might not be a factor at all in the Giro. Contador might be completely fine. Either way, you need to race the race, put your rivals under pressure if you can and play to your strengths and those of your team mates.
Uran might be coming into himself, and needs to start making time up. Should he not go for Aru today as Contador may or may not be in trouble?
