What are you on about with Rolic and Kuss not being able to influence the choice to attack?
They are all on the same radio channel. When Vingegaard called up the car to ask if he should attack, they obviously both heard it and could have chimed in if they disagreed.
Also everyone seems to forget that at that point JV was out of Doms, Valter was the last one and he was cooked, so JV either had to attack to force the other teams to chase, or possibly comprome 1 of their leaders to ride tempo and run the risk of getting planted when others attacked.
So from a tactical perspective it was the right choice for JV to attack at that point - it might as well have been Roglic or Kuss - but apparently Vingegaard got the idea and was first to call it.
Forget about "calculating bastard" or "naive do-gooder" - it was the right call TACTICALLY.
The only problem was, which nobody could have forseen, that the other teams just flat out refused to chase, but blaming Vingegaard or JV for that makes no sense.
I don't think they usually hold long meetings during the final of a stage. Either one rider calls the shot, or the DSs do. But it doesn't really matter how smart it was, the action still created tension within the team, which may or may not have been avoidable (on that particular stage at least).
I see you ignoring the point about Roglic attacking Kuss and riding away from him - I wonder why
It has already been explained/assumed on here, that Roglič was just returning the favour.
