it's funny how everyone who is involved in Moto GP professionally says the pressure got to him...ie Mick Doohan, Randy Mamola, Rossi, people who actually race in Moto GP. One would think they have a good idea as to why Stoner lost it. In the press after the race Stoner said he knew Rossi was cutting down the gap little by little, he said he had to push hard to open up the gap or at least keep it steady but by doing so made a 'mistake'. What do you think a mistake means....A lapse of concentration, maybe because he had Rossi on his mind? meaning he felt pressured to push harder than what he was capable of , thus low siding the ducati. And maybe, just maybe Laguna Seca had a bigger impact on him than you Stoner fans would like to admit... and he did not want a repeat of Laguna Seca so in order for that not to happen again, he tried to runaway from Valentino's grasp.... but he failed. Now, i'm not picking sides at all, i think the 2 of them needs eachother whether they know it or not right now. Valentino needs to be challenged or else he gets bored with racing, and Stoner needs someone like Valentino to pressure him so that he learns to deal with it and become a better racer.
