"How do you figure that?? Are you comparing Casey in his prime to Rossi in his old age after winning 7 titles already??"
No, I'm comparing the 3 of them racing together... was Rossi not 28 when Casey 1st beat him in a championship (when Rossi only had 5 championships)?... or are you saying he was past it even then?... are you in fact saying he's past it now? Fair enough. Joey Dunlop was 48 & still winning TT's... I think he still may have a few wins in him but you want to write off Rossi at 33?... strange.
"is that the work of the dominant rider?? not really.."
You don't read to well, do you?
"The reality is that casey despite his ride around anything tag needed the very best kit available and the competition to be on crap to win the title both times."
So did Rossi... unless I missed him winning on the Ducati?... I didn't miss Stoner manage that though... lots.
"Last season given stoners age and bike Rossi would have walked the title and already had this years sewn up"
At Stoner's age, & on the bike that had won the championship for 2 years running, Rossi got handed his arse by Hayden if I recall correctly... the next year it was the turn of young Aussie in his 2nd year in MotoGP riding a Ducati that no-one else could ride. Both those years he was riding the bike that he was, at the time, widely credited with developing. Apart from his time at Ducati you've managed to choose the worst period of his career to compare.
... do you actually think before typing?
