Kuss is not used to being the guy calling the shots, and Roglič is too passive aggressive to voice his concerns right away (maybe he has to speak to his wife first
)
I'm not saying Vingegaard did much wrong, but I can understand why Roglič wasn't happy about it afterwards, cause to him it felt like a stab in the back.
But it ultimately falls back on the team for having not handled the situation in the best way possible. That said, I doubt it would have been easy for Plugge to have kept them all happy if he had been around for the whole race.
