Interesting reading here.
As it pertains to Ducati and Rossi, what I will say is this, the partnership is not something that can be rationalized into nothing more than a blip on the radar. I've personally felt it is a serious mark against him. Part of the measure of a rider or a driver, is how committed they are to a team. I've always viewed the Ducati adventure as a case where he had no interest in sticking around to try and build something there. Part of the mark of greatness is the willingness to try and build something great. As much as I dislike Michael Schumacher, what he did at Ferrari in the 90s was what Rossi had the opportunity to do at Ducati. Yes he was a bit older than Michael was, 32 to Michael's 27. But in terms of legacy, if he managed to not only redirect the focus of engineering at Ducati, but turned the Desmosedici into a multiple championship winning bike that didn't require Casey Stoner to have success, that would have been in my opinion, an insane legacy to have. Michael is best known for jumping to a team in 1996 that hadn't won a driver's title since 1979, and hadn't won a constructor's title since 1983. He also had the drive and motivation to build something in a team that was much like Ducati by the early 90s; holding onto the belief their legendary V12 engines could deliver championships, pursuing chassis design that was not capable of beating the top teams, all while hampered by that very Italian management structure...oh to say nothing of their chief designer in John Barnard opting to live in England rather than Italy. They put the driver in place along with the technical staff, and they worked their ..... off to build something.
There's a part of me that simply cannot respect that cut and run ..... I can respect his talent, but I question his commitment on some level because of that episode. Yeah I get he didn't want to stick around for a rebuilding project, but he never should have gone there from the get-go if he wasn't interested. I know Rossi is about as driven a competitor as there has ever been in grand prix motorcycle racing, and his legacy has been his main motivator....and he believes winning grands prix is the best way to cement that legacy, but so is building something great at a place like Ducati which was not the well-oiled operation Honda and Yamaha have been for decades. Sure he achieved amazing things with both manufacturers especially with his switch to Yamaha, but that Ducati adventure can't simply be ignored or trivialized as a misstep, and one that happened to set Ducati on the path to redemption even if he didn't stick around.
Maybe that makes me a piece of .... for holding it against him, but I personally can't just look past it and shrug while saying, "Oh well .... happens."
