I don't think he really had it in him, and probably backs himself tomorrow. He was in wheel-following mode, which is more understandable. Trouble is that Roglic also probably trusts himself tomorrow, and so does Almeida.
The top three here really, really lack variety in profiles. I think that has not helped the race at all (and to be honest, would not have been helped by Remco either). There's no Quintana or Dumoulin, with Nibali or a Froome in the mix. It's just decent climber, better time triallist, grinder. When you have three riders with overlapping strengths (and similarly conservative mindsets) it creates a terrible race.
