Rog is becoming the new Contador with all his crashes
It's probably way too soon for me to say this (& he'll feel like sh*t right now), but from a glass half full perspective I'd suggest he was actually very lucky with that crash. It could have been way worse. Like on a spectrum of Beloki & Froome 'worse'. As long as it's nothing career threatening I'd say he lives to fight another day, whether it's literally today or maybe just next season. We know this because there was nothing more devastating than losing the chance to contest the TdF again last July, but he still came back in this Vuelta & was building form again. No introspection, no self-doubt, no second guessing his own ambition.
One thing is for sure IMO: he won't change. It's pedal to the metal No Risk No Glory all the way & next time he'll win.
