Serious Sam still thinks, thanks to his out of nowhere "datas" that Froome was "probably" - somewhat - somehow - in a way of thinking - stronger than Contador in the Vuelta 14'. Poor guy and poor trolling. But indeed, Alberto only out sprinted Froome on farrapona and ancares lmfao. He was toying with him, could've ended him earlier but no point.
Froome tried attacking serveral times and AC responded easily to all his attemps and had still something left in the tank. He was stronger at equal form, deal with it.
But yeah, to answer the question, I'am sure Contador will be able to "put the hammer down" and drop Porte's ass like he did with Froome at Ruta del sol, Vuelta 14', Dauphiné twice (Montagny + emausson), Vuelta 12' (oh froome was 10 minutes off, doesn't even count
)
