1) Giving your main rival a minute in a decent does not conform with allowing them to ride away and patiently getting them back. If you're a good decender you don't just let your main rival ride away from you like that on a descent.
2) sure, BMC's team looses to Sky on all fields except decending, but look at this:
Where are the flats? I don't see them? Wiggo needs to not lose a minute in every descent finish to Evans, Nibali and Samu in these stages, but can he? Today implies it is at least difficult for him to keep up with these boys in the descent. Tomorrow will give a clearer indication of Wiggo's descending skill's. All I'm saying is that today implies Wiggo's descending skill's to be significantly inferior to Samu, Nibali and Evans. In the stages posted above that will be a problem. Tomorrow we'll know more.
And now I have enough of arguing with Sky fanboys, I'll come back tomorrow after we have a more clear indication of Wiggins descending skills. Bye bye Sky Fans, sleep well and don't you have nightmare's about Wiggo being dropped on descents tonight!
