This stage will necessarily make Pogačar much more expierienced and force to feel way less careless. If one aims to win multiple grand tours consecutively, there's no point proving superiority at every terrain possible. Van Aert, Matthews and well as cobbled specialists have their own territory to dominate and stop authority. To each his own. For sure, one might try to be the best everywhere, but then one runs a risk of going into meltdown on the day like this in high mountains. I'm sure this defeat will harden him immensely.
