I mean it used to work, well at least sometimes, if it doesn't work any more then i don't feel Visma currently has an answer anyway. They will follow this plan through and that is that. As for messing with Pogi, trying to keep him in yellow, that is exactly what they needed to do and ultimately failed to achieve today.
It wasn't a common occurrence at all.
In 2022, Pogacar was tricked by Roglic, and a few kilometers ahead, on the Galibier, he was alone against four Vismas.
In 2023, he simply didn't have a good enough preparation.
It's becoming a generalization when Pogacar has been the best rider in long efforts (250km races) and has won four GTs and three other podiums.
He also won the Tour after harder seasons than Vingegaard, which has proven him to be a cyclist with more resilience than him.
