@johnymax said, while his long TT was horrible in the giro he started with what I think was a 4th place in the prologue so.
At the end of the day there is no definitive answer. In retrospective I probably shouldn't have written my posts in a way that sounded like I thought I had one. But while one can point out the comparison with Majka, claiming this shows Lopez is stronger here, you could as well say the comparison with Lopez proves Majka is weaker than in the giro. (Btw despite finishing in front of Lopez in the giro, that was only due to Lopez' crash on the final mountain stage. Over the whole giro Lopez was clearly better than Majka, although tbf not by as much as he seems to be in this vuelta)
To come back to the beginning, the whole discussion started with whether Quintana/Valverde and Lopez are comparable in strength to Landa/Carapaz and Nibali and I stand with my point that they are not. Valverde and Quintana just remind me too much of their former selves from one year ago where they looked like the big danger for Yates before fading into mediocrity the longer the Vuelta went on. And Lopez, even if he is a bit stronger than in the giro, I still refuse to see him as a threat comparable to Nibali.
