Yes, except Stoner was constantly moaning about the bile at Ducati, yet showed no ability to turn things around.
Instead he regressed. Who gives .... about development? I'm pretty sure the Ducati engineers weren't thrilled when their rider wasn't able to give them good feedback. Hence they weren't bothered about seeing him leave and targeted Lorenzo and Rossi.
Of course many people view that as s mistake, but what will people say if Rossi is able to make the bike more rideable, and be fast on it?
Actually, I already know what you will say - 'But, but Rossi had Ducati's ear!'
Actually he never moaned publicly about the bike while he was at ducati, nor did he moan about the lcr honda or its michelin tyres while he was contracted to them; traditionally known as being professional I believe.
If valentino fixes the current bike , great congratulations will be in order. If this requires a change in the engine configuration and a change in the chassis design for the next bike, but it is nevertheless a good bike, plaudits will still be his due but I don't see that much blame will attach to stoner.
I think they went after lorenzo because they thought stoner was flaky and that lorenzo would be better from the public relations/promotional point of view, although I am not sure the latter is necessarily true. This year will demonstrate whether lorenzo has bike development ability; I am not sure there is any more evidence that he can develop than there is evidence that stoner can thus far, although he obviously is pretty good at setting up bikes.
