It's tough for Dan Martin to use different strategy. If he initiates attack earlier, he risks his whole race. If he escapes alone, or in a weak group it's suicide. The best scenario for him is to wait for some strong rider to attack (Wellens, Kwiat, Gilbert...), and then to leach on that move. But that would hardly pass without Valverde's presence in that same group. It's just so hard for quality break to escape in this race. Maybe this year will be different with the addition of Redoute and Vecquee. Teams who want to attack earlier should really have to up the pace on that climbs, and already start to attack on the first passage of the Mur. I'm talking about Lotto, Sky, Astana, UAE, Quick Step here... Teams have a choice here. They could ride a controlled race here and have a nice view of another Valverde win, or they could try to create chaos, and then only God knows who will win. I know what will I choose.
