Winners:
Wiggins - no explanation needed.
Sagan - simply amazing, just dominated
Purito - May not have a lot of absolute wins but he fought hard with a true heart.
Hesjedal - he defeated the odds and won a GT. Not an accomplishment to overlook for someone of his skill.
Losers:
Frandy - poor performing, boring, unmotivated, why are they still racing?
(orders of magnitude difference follows):
Cancellara - sole strategy has become too predictable; poor team support
Hushovd - He's finished.
Evans - No luck.
Menchov - built up for the Tour and failed massively w/o due cause.
Neutral:
Vino - the Olympic gold saved him from the loser list.
Gilbert - ditto, exchange for Worlds.
Cavendish - Only paled compared to his own prior self and not in absolutes, though the loss of Olympic gold really made him look bad in front of the non-cycling world so not a winner.
Contador - obviously did well for what he did but being omitted for most of the season doesn't rank him to the winner list.
Freire - declining but still had a few wins here and there to prevent embarassing himself. Good that he retired.
