I only question Amstel and Flecha, I did so before Amstel.The fact his fans are now starting to question his race schedule suggests chasing all these one day races so aggressively this season might not be the smartest thing.
You have to all remember he's literally leaving 100% guaranteed wins in races like Paris-Nice, Catalunya and Itzulia on the side when he chases the classics. Just imagine how many WT wins he could have by now when you addition the overall GC + innevitable stage wins he'd get? He'd be destroying records by a much greater margin than he already is. And Amstel is in no way more prestigious than a win in any of those stage races either.
I still think Pog can demolish Liège, mind (after all he was beaten by Vinge at le Lioran in the Tour last year and then demolished everyone a few days later in the Pyrenees), but the "all-in on one day racing" strategy only works if he wins them. Right now, he's lost 3 out of the last 4 he competed in.
I never question MSR, Flanders and Roubaix, and if Pogacar´s fans question this hey should like other riders.
Pogacar is more than just easy wins in Paris-Nice.
If Pogacar wins four Tours like Froome, he won't transcend the same level as Froome, better.
Indurain won five Tours, and no one considers him at the level of Hinault. There you have the answer.
