I agree that Quintana isn't the most adventurous rider (I'm a fan BTW), but it's not exactly easy to attack the best climbers in the world who are in their best form. In the Giro there was one stage where Quintana did attack and when Dumoulin caught him at the end he lost some time. Yesterday it was clear that he didn't have the legs after he couldn't follow Froome and Porte. It would also be stupid to attack early because the Sky team will just keep you within reach until Froome closes the gap because he's still fresher.
Basically, it's not Playstation.
obviously it's not a video game. i know how this works, i've been watching pro cycling for over half my life. no need to be condescending.
a short punchy climb with a massive gradient would have been a perfect time for a pure climber like quintana to attack. it may not have amounted to anything real in terms of time but it would have required the other contenders to expend energy bringing him back on a 20% slope.
as far as the giro goes it's pretty obvious he needed to attack on stage 20 regardless of what happened previously, and he didn't even look like he was thinking about trying it. he clearly knew the situation in terms of his chances in the TT and the state of the race at the time and did not act on that. he was obviously not riding to win for whatever reason. i would have respected it if he had made an attempt and failed. but when you have no choice but to be aggressive or lose a professional grand tour, to not even make a single go at it is plain lazy, or the rider is injured. we know he wasn't hurt (beyond the usual grand tour fatigue that everyone would be experiencing), so...
obviously now we know that he didn't even have the legs to stay with the main contenders on la planche (how badly is movistar missing alejandro valverde right now), but if he was in his top form it certainly wouldn't have been a poor move to try to have a dig. at least it would have separated the field a bit and provided valuable intel on the status of his rivals in advance of the alpine stages. it's all moot now though. it looks like he gassed himself going for the giro and doesn't have the form to stay on the podium this time around.
i've been a fan of nairo's since his first tour - he's a great climber but his downfall is he just makes weird tactical choices that make no sense (like just letting froome ride away downhill last year on the peyresourde and assuming someone else would do the work to chase him down). i also think that movistar's focus on him winning tours isn't helpful. quintana is clearly one of the top climbers on earth, but valverde is, in my opinion, a better overall rider when you factor in tactics, time trials, energy, etc.
this turned into a rant, guess my 3 cups of coffee from this morning are now kicking in.
anyways, all i came in here to say originally was that edvald boasson hagen got fucking screwed this morning - that was a dead heat and they should have both been given the stage win.
