Both Nicky H and Stoner had asked for a "softer" bike on numerous occasions.
Stoner was very vocal over the biggest symptom of the problem, a lack of front end feel.
Of course, this was labeled as whinging by internet fanboys, and when asked about it in a interview last year Rossi said "I think it is in Casey's head" with his trademark smile.
Suffice to say the smiling stopped when he had to ride the Ducati.
As Ash points out Ducati had decided which way the project would go, and all the time Stoner could pull out the odd race win they obviously didn't see fit to make dramatic changes.
This year Rossi won't stick his neck out like Casey, and they can't be seen to have the one of the best riders in the world to be going nowhere on their bike, especially as Philip Morris have raped their petty cash box to have Rossi in there.
