His signing was still something of a fluke. As I recall it was partly on Troy Bayliss's recommendation, to wit no-one gasses it up like Casey; I believe he was their 4th choice, after Melandri of course who was unavailable for that year but also Nicky Hayden(I think) and John Hopkins.Not to be pedantic, but I never implied Ducati had in their wildest dreams predicting a championship. My point was simply that they saw potential. The field of available candidates for that seat was limited, and candidates with better track records still more limited. Ducati surely didn't care about Dorna rating in the wake of Stoner's wins.
As to his quitting: Agreed. Pearls before swine. Tho what with his machinations to fabricate artificial scenarios leading to more wins for Rossi for the sake of ratings, I tend to think of Carmine as the Vince MacMahon of racing.
OTOH - the whole soap opera made for some really fun discussions on this forum.
Enough of Casey I guess, it is 9 years since he started his last motogp season.
