I think any stoner fans casting doubt on dani having physical problems have very short memories which don't extend back to even 2009, let alone 2008. Stoner in 2008 and rossi in 2010 also demonstrated that injuries don't hurt as much when you are winning, so dani faltering when passed is a natural reaction and not suspicious in my view.Stoner is also directly quoted in the sydney press this morning as per bunyip's link that he decided to push when he saw dani had problems.The other thing is that dani whilst fragile physically is a warrior, and has raced with horrendous injuries in the past.
I guess it is possible though that arm/nerve problems compounded dani's and/or the honda's frequent previous problems with maintaining pace late in races, and that some of dani's despair was because rather than slowing the honda in stoner's hands appeared to be getting stronger as the race progressed.
I am not sure what to make of casey's pronouncements post race; he perhaps was just telling the truth as he often does by proclaiming he had plenty in hand and was now following mick doohan's advice about winning at the slowest possible speed (a dictum of jack brabham's many years before mick I believe), but if so leaving the opposition guessing may have been sounder strategically.
