Sure thing bro. They were on the juice at 16. That's heading into the really cynical part of the Clinic. You go there they give you a special uniform to wear.
We've all got the cyclists we believe had it always. For me, nobody on Sky except Lokqvist and Boassan Hagan have anything resembling incredible natural talent. We already know how one of those stories went under that roof. In the dead end year of 2010, Lokqvist thumped Wiggins in every GT, not that he himself did any good.
But if it makes everyone sleep easier, keep telling yourself Froome is good. It's like the single mentions I've read of his superior VO2max. More myths from fanboys. Wanna know the real tell? It's how he rides. He looks atrocious. Praying Mantis on a bike. No natural pre epo GT rider rode a bike like that. But they sure as hell rode em like Contador and Schleck do. Think about why that is? Cycling is an art as much as it is an endurance event. Both go together at the pointy end of the spectrum.
But like I said, if people can sleep easier or get their jollies from watching a guy ride a bike in as ugly a fashion as Froome, knock yourself out.
