Pog absolutely could win PR if that was his focus.I have done flanders and PR. The difference is immense. You really can't compare the cobbles of Roubaix with the cobbles in Flanders. Flanders cobbles are nothing compared to Wallers, Mons en Pévèle et Carrefour de l'arbre. Pogacar is unbelievable but he can't win PR. Not in a million years. You can't compare with the Tour de France stage either because there are only a few secteurs and they were not the hardest.
