Hard to assess because I think the stages we have seen so far are very different from the ones who are still to come and decide the GC.
Also the two biggest favourites at this point are very young and have each their questionmarks with health / form, which even they themselves probably don't know everything about. And it's not like they have raced a thousand GTs already, so that we know what roughly to expect.
Bernal obviously looked best so far.
Evenepoel can count on his time trial.
What will happen in the mountains we don't know.
I wonder whether the Strade stage might already decide a lot.
Vlasov looks like the best third contender to me. With that strong prologue who knows if he isn't capable of producing a similar time trial at the end? I expect him to be very strong in the mountains, but nothing hints towards him being better than Bernal / Evenepoel, so unless they fail I can't see him winning. Looks very good for a podium though, especially since I think the stages so far have not been those he's best suited for.
Ciccone is exciting, could be a serious contender or blow up on the hard stages and his time trial should be... well, not something he can rely on. I'm inclined to say he's going to blow up eventually, but he could be the real surprise package.
Then we have... Caruso! Well, if the others fail.
Dan Martin - no, the time trial, if nothing else, will be his downfall.
Yates is out for me, I have no idea what happened. If he didn't get sick he should probably switch the coach, the team... because how can it be he was so dominant two weeks before and then just... I don't believe in his resurrection after he didn't show that much on any of these stages.
Martinez, unfortunately will either crash or be used up as a domestique entirely.
Hugh Carthy I just don't believe in for unclear reasons. He looks vulnerable to me. But maybe that's just because he's so skinny.
And I don't see anyone else, either. Hoping for a very good place for Bardet, no more games please, DSM should support him fully. But with his time trial I think he will try to attack and maybe he can do something great on the sterrato.
Obviously I won't vote, since I don't have a clue.
