There's only a few explanations that make sense to me, and the no radio etc don't make a lot of sense to me. He got dropped like a stone in the final. That's not lack of tactics, its a lack of legs. Considering he hasn't done too well in one day races in the past I'm starting to think that - either he doesn't recover very well from efforts over threshold during a race, or he just needs the few extra days of a GT to have a great day and can't just be sublime out of nowhere.
He didn't want to risk a DNS on wednesday by going full gas down that descent when Nibali attacked. The main surprise was that he didn't follow Purito's attack. Whether that was because he realised the race was over for him or because he wasn't strong enough, idk. I definitely expected him to be a lot stronger though, which doesn't bode well for the Vuelta.
At this point, another Vuelta podium is useless. He has to go for the win, which looks unlikely
