while I would love to see Ducati take the championship again, and Stoner could do it, I worry about the whine/butthurt factor. Stoner left Ducati with hurt feelings and butthurt. He just left HRC because his feelings were hurt because they picked Aoyama to sub for Pedrosa instead of him, and Honda didn't listen to his feedback about the peaky power delivery, so he cried/whined about that as well.
Ducati knows their guy - once they caught wind that he was full of butthurt and hurt feelings, they knew he was ripe for poaching
