Your point about Gianetti also has much history. In light of the fact that every American DS on the Big League level has also been involved with enhancements and busted riders suggests it's a matter of opportunity and evasion; not morality.I don't see how O'Connor's second at the Vuelta is all that shocking or puts Pogacar's year-long performance in any less dominating perspective. If Pogacar were on any other outfit than the one managed by Mauro Gianetti, I'd be less insistant in claiming something is awry. Next year we'll see a less victorious Pogacar, as he himself has said, to prevent "envy" from making things troublesome. If you can believe that.
As far as Pogacar winning less it'll be down to other major players to quit racing to not lose too much and actually race. Time to unplug the wattage meters and let them race on speed and heart rate data without DS manipulation. IMO too much data has led to risk paralysis.
