I don’t necessarily se TJV’s position as so rosy. There is is scenario where they get f**** pretty easily.
1. Say Vinge is worse than Remco and can’t produce a meaningful attack. That’s pretty likely.
2. Say Kuss is just good enough to follow Remco but not better than him. Also possible if not likely. In that case, he won’t attack but will hold on to his jersey. And in that case, Roglic probably won’t attack either because TJV would consider it too risky.
Then all that needs to happen is for Kuss to crack later in week 3 and Roglic not having enough time to overtake Remco…
I think it'll be much more straight-forward:
The strongest riders will push on the climbs (Ayuso & Mas in particular will be catalysts), with Evenepoel doing what he usually does: setting as hard a tempo as possible to either blow everyone off his wheel or limit attacks. Think back to Sierra Nevada last year.
I might be simplifying this but I reckon tactics are only one part of the story, i.e. legs will do most of the talking. Whomever is the strongest will likely win. That includes Evenepoel as well. I mean if he blows Rog, Kuss & Vinge off his wheel, he's going to win the Vuelta.
So from Rog's perspective, he just has to keep on doing what he's been doing over the past week: attack Evenepoel when he can & take time when he can. And I feel fairly confident he can do exactly that on quite a few of the stage profiles which remain.
