I disagree....completely. See what Hinault did the next decade, what Pog beginning to do. Even today, with modern bikes, on short notice like Merckx did, how many can do 49.5 in an hour, let alone riding Merckx's '72 bike? How about beating Patrick Sercu in '74 in a velodrome to win the last stage of a Tour? Descending? Vincenzo bows to the master. It's unfair to compare anyone to Eddy. He's the Jordan of cycling. The Boonens and Cances, Sagan, or Froome*, great riders are nothing compared to him. But Pog is interesting. In the era of whatever advancements...he wins big. If he keeps winning, he'll be there with the bests of them.
Indeed Pog is interesting, but can we expect him to win a combo such as this: 7 MSR, 3 Paris-Roubaix, 4 LBL, 5 Giros (5 Tours, perhaps, but not 5 + 5), no way sir. Not a chance. And this precisely confirms what I essentially said about Merckx's palmares being unassailable today. So the bolded statements appear contradictory in that you first claim to categorically disagree with me , but then go ahead to fundamentally confirm my point that it's not possible for a rider today to equal Merckx in the range and number of victories.
Hinault rose to the top very soon after Merckx's exit. The Badger was certainly a phenomenal rider, but, like Merckx, benefited from a sport still exclusively bound to European mores and tradition. GT riders still rode the classics. The Giro-Tour combo was frequently undertaken. Vuelta in April not September, etc. So there were not the giant peaks of performance today's riders plan for, which necessitates sacrificing certain events to reach a higher level of fitness for targeted races that has caused intensive specialization to progressively take over. It's thus inconceivable today that a rider could hold good enough form to be competitive from PN through the classics (MSR, cobbles and Ardennes), through the Giro and Tour to then finish with Worlds and Lombardia. But in those days with riders like Merckx and Hinault against fields that generally raced together from March till October it was. During Hinault's career things started to evolve, however, better physiological knowledge of training regimes, improvements in bike design and components (for example, clip pedals and shoes), the arrival of excellent non-continental European and non-European talents from Ireland, Great Britain, USA, Canada, Australia, Russia, Columbia and so forth. And then there was the stuff which can only be discussed in the Clinic. The sport begain to change dramatically as it continued to do though the 90's till the present.
I really don't see how you disagree with me, therefore, despite your assertion to the contrary.
Unless it has to do with the second part of my post in which I pondered over whether or not a talent of today if taken back to Merckx's time, with the same methods and equipment, would be able to duplicate what the Cannibal achieved. Frankly I have no idea, of course. But it's probable that because today the pool from which cyclists are drawn is global, there must be someone with an enginee as big, if not bigger, than Merckx's. Although this alone is no gaurantee of achieving so many winning results. Ineffable qualities of will, tenacity and tactical nous are likely almost as important. Arguably though based on the sheer aerobic and physiological traits in the 80s already Lemond had a bigger engine. Yet Lemond fell far, far short of Merckx's palmares and even Hinault's, who he certainly bettered at the Tour in 86 when the Badger, by all accounts, was in the best form of his career. True Lemond was likely hampered in the beginning as an American pioneer on a French team in a Euro dominated sport, at a momment when two incredible French champions were at the top of the sport: Hinault and Professor Fignon. So it was not easy for Greg initially to have his chances to shine, except at his first World's title while unsurprisingly riding on his national (not club) team. Then, of course, he almost was shot to death at the height of his powers. So an incredible amount of time and energy was necessary just to return to the top, at which point, however, the dawn of a new era was on the rise.
But I digress. To return to the main point, so whilst it's impossible to know if a cyclist today could go back to Merckx's era and be as succesful as the Cannibal, I bet there is someone in current cycling who has superior physiological capacities just because the pond is so much bigger ("big fish in a little pond" vs. big fish an an ocean sort of thing). Is that Pogacar? Could be or could be someone else of whom at present we are totally ignorant.
