I can’t believe you write such contradictory comments. You constantly mention defeats against Nibali and Froome, even though that was when Roglič had just started his real cycling career. And even in that Giro, he crashed and got sick in the middle of it. That’s like comparing Pogačar’s loss at the Vuelta to Roglič and then using that, if the latter had ended his career right after, as a lifelong argument that Tadej isn’t the GOAT because he lost to Roglič?First of all, I don't answer stupid questions specially when they hide important informations. Why did you mention Valverde, Purito, etc and didn't mention Nibali? Very smart since he beat Roglic. Then you don't mention Contador too.
"Cycling is much bigger than the TdF". Yes it is however for a GT specialist (with only a LBL win to show. Sorry, cycling fans in general don't rate TTs very highly, even worlds or olympics), not winning the Tour is a massive hole. Roglic is not Boonen who won 4 PR and 3 RVV.
Roglic has 4 Vueltas and 1 Giro to show. Tell me a cycling legend (those who fight for the GC) who didn't win the Tour?
His racing style is not the most impressive one. What the hell is remarkable/legendary about Roglic? Even Vingegaard is not a legend and it is probably the second best GT rider (in ability) of all times IMHO. Palmares is very important to gove the status of legend to riders.
You mention Jonas as probably the second-best GC rider of all time—based on what exactly? Because he competes in the era of the best? And if he’s second based on that logic, then Roglič must be the third-best GC rider of all time. Or do you think that this statement (“that Jonas is probably the second-best GC rider of all time”) is proven by numbers? You use arguments and twist your own logic however it suits you.
Roglič is definitely a cycling legend, who would have had incredible achievements if he had started cycling from the beginning. In the Froome generation and others, he very likely would be sitting on 10+ GC wins by now.
