As much as I admire LeMond for his accomplishments I think his assertion that the teams should collectively attack Froome, is off. If Froome cracks, I see now way that will happen to any devastating degree, then I agree. The way I see it, if the top 3 guys on Sky are are stronger than your team leader, there's no good reason to attack....Even if you could....it's suicide to your podium chances. The only chance I see, is to sit tight & hope for him to do himself in. Seemingly improbable, in itself. Froome having a bad day now would likely cost him 30sec. He'll take back more than that by the end of the tour.
