And there's the weakness of Sky, after the Vuelta two years ago the once again show they have no idea what to do if their team leader is not at his best. With Uran / Henao they have two riders at least one of which could podium (heck Uran could've taken the pink today) but they make both of them give up everything for someone who clearly does not have it right now. It's not like they saved him anything.
Actually it looks like Wiggins gave up, so Uran and Henao are going to lose significant time to help someone who has no interest himself anymore.....
