True.And people wanted him to do the Vuelta as well.
With that modern calendar, Vuelta last and the times in between, Merckx would have done it. Hinault too. But no one has done it, it's apparent to me that doing it would have amplified the "D" suspicions. Pogacar would have won this Vuelta by 10 minutes, or on my scale 8 minutes, let's be real.
Having said that, Merckx won 7 MSR, an insane (and not soon to be broken) record: Tadej can do the same in Lombardia., Coppi has 5, Merckx and Hinault 2. He can do 4 in a row and be back for more. Scary....
