Sure, but i think we can all agree that Evenepoel is not just ''considering someone top GT favourite because of winning few one week races without GT level competition''. First of all, he beat GT level competition, i have no idea why people keep acting as if beating Carapaz, Landa, Gaudu, Lopez, Roglic, Kelderman, Vingegaard, Yates, Hart... are all nobodies when it comes to GT's. Because he has beaten all of them in GC races, most more than once. Secondly, i think what he has shown throughout his short career is proof that he is an extraordinary talent, and not just another guy who just can get results in small races. Two WCC and two ECC ITT medals, from the age of 19 onward, shows he has a huge engine. Youngest winner of Liège since the late 1960's by telling everyone smell ya later. Two entries at Classica, two wins in dominating fashion.
The problem is that every time he doesn't perform, people take it as evidence that he can't do it. While every time he succeeds, he still has everything to prove. But when other riders finish 20 minutes down, the same does not apply and they remain contenders. Regardless, i agree he still has to show it in a GT, but acting as if the potential is not there is simply stupid.
Pushing watts over a certain period has little to do with the opposition, or when exactly in the season you push them. If it is during training or during prep, 6.5W/kg over 30 minutes is pushing 6.5w/kg over 30 minutes. Doesn't matter if it's in the Tour or in Langkawi. Your ridiculous description of his performance in Itzulia (where his rivals were actually working together against him) is quite telling of the agenda you are trying to push here. If you are annoyed, you are doing it to yourself.
