Remco is still the big favourite, but Roglic had a strong first week with a smaller then expected time loss & no real impact/time loss from the hectic sprint stages.
Thomas is where he should be if he wants to win and he also looks on, so it seems like he could be more then just the odd guy riding behind the two big names like in the Tour.
The surprise ist Hart. He was strong in ToA, but he looks like he can really challenge Remco and Roglic and I didn't saw that coming. I'm not sure if Ineos can make something out of that numerical advantage also with Arensman, Sivakov and de Plus close enough that they have to be chased at a point. They are the strongest team that's for sure.
I bit underappreciated in my mind is that a lot of peopel are still close in GC. After one week losing 2 minutes you normally say it's pretty hard to see that person really competing but the time gaps could be huge in the last stages with people in the Top 10 cracking left and right (+the covid/sickenss problem in the peleton). If you are on in the third week you could really change the race.
Caruso and Vine are my dark horses who could still be on the podium, but I also didn't expect Vlasov that close and Almeida is of course in a good position. Haig or Carthy already proved, that they can climb on a GC podium with big third weeks. They have to be lucky and on good form but it's possible. Lopez was on 2:34 at this point in the Giro 2018 and ended on the podium. if you are on the happy side of motivated split in one of the big mountain stages a lot is possible.
