There are so many variables in cycling in a year that it is hard to judge until we can look at it few years in a rear. Two years ago Mas was podium at the Vuelta. Few years back it was Chaves. Hec in 2011 we could have said The Vuelta was the weakest of them all with Froome and Wiggins fighting for the race with Cobo. So many things change from year to year.
