There was no need for him to push hard on the cobbles. He was comfortably in the lead. He's always crashing for no reason and then having knee and back issues. He has had several knee operations or "scopes" over the years due to these crashes. There is no need for him to take risks because when fit, he can pick his moments in safer locations during the race. He is his own worst enemy.He's always pushing and I feel his crashes are often ones where he slides out as he finds (and passes) the limit. One naturally puts ones arms out to steady oneself meaning thats often the first point of impact on the ground, but also his knee is another first point that contacts the ground first due it being obviously closer to the ground.
