gw is 200 km (210) on cobbles, so not strongets participants there and the 240 km giro d'italia stage was in a break in a grand tour, nothing like a 1 day race in toughness, even boom did well in over 200 k stages in tirreno last year
Yeah, a 200+ stage in a stage race can't be compared to a real classic. In the big classics (MSR, Ronde, AGR etc.) you have a strong field, a tough route, with a lot of kilometers in your legs. I requires much more endurance (or a bigger engine, or whatever you want to call it) than a long stage in a GT. A longer stage in a grand tour just means you're sitting on a bike in the peloton an hour longer, nobody will suffer more because of that. Just look at a race like Vlaanderen, it's starts to get hectic about 20 km before the Oude Kwaremont, the race pretty much doesn't slow down for the last 100km, whole teams trying desperately to start the hills in a good position, sprinting up every hill etc. That's why you need a big engine, a long stage in a GT isn't comparable to that at all, and doesn't prove you have the engine to handle the big classics.
The Gilbert comparison falls short. He already effortlessly finished in the front group in Milano - Sanremo and Paris-Tours when he was 21, when he was 22 he finished 6th in Milano-Sanremo. He had that big engine from the beginning, it was just that his climbing was far too weak to perform well in the other classics. The Hushovd comparison is more apt, but he had a completely different build up, he started at a moderately good level, and improved on that imcrementally every year. Boasson Hagen on the other hand is someone who burst on the scene, and showed tremendous promise from very early on. Hushovd is someone who only reached his physical maturity in his late twenties, can the same be said about Boasson Hagen?
I'm not saying the clock is ticking or anything, he still has time, and he has had some bad luck with injuries, but a guy like Boonen finished third in Paris-Roubaix at age 21, Gilbert 6th in Milano-Sanremo at age 22, Cancellara finished 4th at Paris-Roubaix at age 23, Freire was world champion at age 23. The really good guys usually show they can handle the distance really early on.
