Do enlighten me how Merckx, cooked from mechanicals and chasing, would beat a guy who pulls a lot less than him, has almost 15kgs extra and has a far superior sprint
Unless that was sarcasm which a missed
Merckx has more victories but also twice as many days of competition, like most cyclists of that era, which in turn means his loss ratio is also higher than Pogacar's in the Classics.
He won more, but he also lost more. The idea that Merckx never lost is a myth. He had several notable defeats, but he competed so much and won so much that it becomes irrelevant over time.
Look at the statistics, his number of defeats in Monuments is higher than the number of defeats of Pogacar and MVDP in Monuments.
These debates about the Merckx era seem absurd to me; they're such different times.
Merckx also tested positive three times and was expelled from the Giro d'Italia, but he was allowed to participate in the Tour de France, which he won by minutes. Nowadays, he would have been banned and wouldn't have won that Tour. Everything was different.
