I don't see much belief here in Cadel and I'm surprised.
He already has a comfortable advantage which is likely to grow after the first tt, he's not bad at all in the mountains (especially when he just has to ride defensively), he's obviously excellently prepared and has experience of winning the GT, and maybe the most important - I'm not convinced Quintana or Uran or anyone else can take 3+ minutes on him. Maybe if Quintana repeats his Tour performance, but I doubt he'll hit that form in the last week.
So, it's Evans' race to lose at the moment, imo.
