EPO was a huge buff to performance in cycling. Unless they found ways to do it again that can't be detected yet (microdosing?) or he has a new thing, the gear Pogacar is on is not the same level as Armstrong et al. Most of his key rivals are not there or in poor form, the field is weak, making him look even stronger. These new kids already trained with power meters, optimal nutrition and training, and support. You cannot discount those things.
Anyway, I am all for pro riders having to publish power data along with bio passport. Makes everything more transparent.
