You really do open yourself up to it...
You say be fair, but you are being anything but. You make excuses for Rossi only being beaten because he is on inferior equipment, therefore no comparison can be made. But you have no problem with the years that Rossi was on top drawer equipment and other riders weren't. Then it was a case of Rossi being better than the rest.
As an example - He is still more than capable of winning on the right bike whether in GP or WSB.
That statement can and has applied to many riders over the years and some have never shown their full potential because of the equipment they had. It doesn't just apply to Rossi. You shouldn't need to think too hard of what may have happened if Stoner had been on a Yamaha from 2006 to 2010.
You also refuse to accept that Rossi does not like competing on an equal status. Finally Yamaha forced it upon him with Lorenzo and ultimately he walked from the challenge.
If you're going to compare, be realistic.
Benny - you're not serious. That ambition outweighing talent comment was one of the funniest lines ever delivered in a pit garage and it totally threw Rossi who was probably confident of pulling of another of his PR stunts when he went in there with a media scrum in tow. The mischeivous look on Stoner's face when he said it was priceless. No tantrums, no aggro, just a great comeback. Bitter and sarcastic - you gotta be joking man. He was as cool as you like.
Back on topic, the potential of the Ducati can be unlocked with a redesign of the engine's power characteristics according to Capirossi - who has never ridden it...??
