Harmon loves Evans, and Valverde kept beating Evans. Then they screwed over Levi in Paris-Nice, and Team Sky kicked up a stink about it, so Harmon hates them because Team Sky hate them. Oh, and Ventoso was the one who mentioned Cav holding on to cars, and poor José Joaquín Rojas gets a bunch of abuse for no real reason other than that he would have been the benefactor if the anti-Cav brigade had had their way last year.
Movistar are quite often given this kind of bad-boys-of-the-péloton reputation because of that tendency to not play by the Anglophone teams' rulebook of morals and practices, because their having several strong riders but no overly strong contenders means they often try different things breaking up the nice pattern many teams have set for the day, because the Spanish are bogeymen in terms of success and in terms of suspiciousness, because they have some shady names in their ranks, because Ventoso said something about Mark Cavendish 14 months ago...
They've done a few things that were perhaps a bit morally dubious this season, for sure, but at the same time, they had a rotten 2011 and may have decided, you know, to hell with it, we're going to try to win whether we have to upset the cosy cartel at the top to do it or not.
