Sorry but I just cannot agree with this. I have always accepted doping is part of the sport but its also cheating hence should be disqualified as a "talent". It would mean otherwise unremarkable pros can be considered more talented if they are great responders to doping? Armstrong comes to mind.It would be less likely without doping because with doping there are the two factors of aerobic talent/leg muscle makeup and doping response on top of it. Of course those are intertwined but in general, doping adds another factor you can be talented at, thus making the disparity between the outliers and the average pro bigger.
This added margin for error allows those aerobic freak-super responders to fight for victories year round instead of having to focus on one or two main goals.
The most talented riders are those who I think achieve results with less doping - or are poor responders. We know for a fact that some people respond better to doping methods than others. These riders are not more talented. Talent is the physical ability you are born with to race on the road. Genetics. Since road racing is an endurance sport that means aerobic capacity, FTP and recovery (for grand tour racing). Genetically better for doping? Just no.
With Pogacar, of course he is doping. But his results stretch back way before he was associated with or even came to the attention of Mauro Gianetti. Not sure if its can be verified but Wiki mentions Pogi was noticed in 2011 when he was only 9 years old? How many other pros were noticed at such a young age? Pretty sure Pogacar wasn't doping then.
