It like saying that VR is going to walk in and consistently win races for Ducati, as there current rider (s) aren't. And of course using your rather bias logic above, Rossi's record in the premier class..............
As you know I quite often do this for fun, as do you, but my main point was actually that using the same arguments you advance concerning rossi v stoner dani loses. In particular in regard to your attitude to stoner's injuries and illnesses where you said these in no way could be used as arguments as to why his 4th place in the championship last year did not reflect his true status (with which I agree btw) I am surprised you have advanced such an argument on dani's behalf. If you don't want to count 2007 for stoner I will discount 2006 and 2010 for dani; in 2006 he clearly had a better bike than stoner, and I think the argument for him having a better bike than stoner in 2010 is at least as strong as stoner having a better bike than him in 2007. The other problem is that whilst both are too affected by injuries and illnesses to be considered reliable, stoner has had 3 unaffected seasons ( including thus far in 2010 anyway touching wood) to dani's 1, his first. And that is a real problem for dani, he seems to get major injuries when he crashes unfortunately, stoner at least seems to bounce better.
In regard to rossi his overall record is incomparable, and he is obviously arithmetically considerably better than mick doohan let alone casey stoner. Comparing the years where they have actually raced each other though, given that these are the only races where stoner had a chance to beat him, the wins are 25:22 in rossi's favour, not an overwhelming margin, but more crucially 2 championships to one, which obviously still gives rossi the edge, at least until casey wins the 2011 championship
All jokes aside, I think honda hired stoner because dani has never put a season together as tom says, whilst stoner has at least done it once. Before dani's crash, and particularly prior to aragon when dani had 4 wins to casey's none, honda may have shared your opinion regarding next year.
(EDIT Jorge actually needs to win all 4 remaining races to be valentino's equal by season's end, and obviously valentino will still have 2 world championships to 1.)
