I'm not sure. I don't think it's as clear-cut as a straightforward 'no'. Gibernau has lost confidence and been out-psyched by Rossi no doubt, but if he got his confidence back, then I think they could do a lot worse - he has been a consistent front-runner and regular race winner over the last couple of years (excluding this one). He's the only rider to have regularly challenged Rossi, and is still pretty damn quick when he gets it together - witness his taking the pole away from Melandri at the weekend.
Bayliss was a superbike rider who never really made the grade in gp, Checa was an established midfield gp runner, Gibernau (until recently) was a consistent front-runner. On paper it seems like another step forward in the Ducati rider line-up.
Question is, will Gibernau get his confidence back, how will he adapt to the Bridgestones and the Desmosedici..?
I think it's a gamble.
