As I wrote in another thread, Quintana has to win time back tomorrow. Otherwise, it will be death by a thousand of cuts. He can, and a shorter Ventoux isn't necessarily a bad thing. If the attack backfires, time loss may be small. Get a couple of guys in the BOD (there will be one with a Frenchman I won't name in it), and let them drop smart so Nairo has a ladder up the climb, attack mid-climb. It's a risk worth taking IMO.
