Don't be so one eyed. There is no contradiction between winning and being lucky. He was lucky in a number of ways: that Nibali woul commit suicide to benefit him and Valverde, that Purito wasn't strong enough to get away from Nibali, that Valverde had an inexplicable brain fart. These things were not under his control, and he got lucky on all three counts.
He had to be strong enough to be there when riders who would usually be stronger were not. And he had to be smart enough to take the right gambles. But he also had to be very lucky. And there's nothing wrong with that and certainly nothing unusual about it in a sport as chaotic in cycling.
