This fantasy has been rolling around a lot (Radio Shack attacking), so let's dispel it now. First of all, when a team is driving the peloton on behalf of their GC candidate, they are either (a) controlling the break or (b) setting up a move (attack at base of mountain). If Radio Shack rides along until they set up their move, then I'm not at all worried about Lance, Kloden or Levi attacking, because it won't stick because, so far as I know, Lance doesn't have the explosiveness to create a gap any more, and Kloden and Levi never had it. At Paris-Nice, it was a culmination of things (weak team, attacking by group, racing from beginning of stage), but the biggest one was a hunger bonk. He simply forgot to eat enough. He was there until the last 15 KM, which if I recall was no longer a climb but a descent to the finish (he was pedaling squares). I think much as been made of that stage, but no one has been able to replicate it again. More to the point, I don't think Radio Shack has the legs to replicate because, again, they aren't attacking riders (they are all diesels).
Moreover, we've SEEN this exact tactic just last year. Saxo Bank did this on Verbier and Col de Romme/Colombiere. AC covered the first real move by Frank, Lance towed Andy and Wiggins back up to the group, and AC went from 5KM out. On Col de Romme/Colombiere, he covered attacks. He was essentially alone on the slopes of Col de Romme, since Kloden was holding HIS wheel and not providing any assistance. Now, if he could go with two of the best climbers in the business, why would he have a problem manage three good, but not great climbers? Especially when Astana has riders who are equal to them in the mountains (David DLF, Navarro, Tiralongo, Pereiro and Vino).
I expect Team Lance to finish higher on GC simply because they have three good overall GC candidates, but no exceptional GC candidates. They are 2009 Astana without their best rider by a wide margin.
