IMO, a lot of his true fans, who are also big fans of the sport, are genuinely perplexed at the enigma that is this situation, and most suspect that there is something seriously amiss with this combination, that probably won't be fixed-ever
A lot of Rossi supporters only started following GP in 'his' era and are perplexed - they have never had this situation before. They don't know how to behave.
As a supporter of both Wellington and London Irish I have had decades of disappointment in sport to fall back on. When Casey has a bad year, I will be able to function normally.
They want to point to everything possible - the bike, he's sandbagging to get better parts, he wants out of his contract - everything except what is proing to be the most plausible, that he is human and just can't ride the Ducati as well as other riders can.
His media machine has spent the better part of 11 years convincing the gullible that he is the second coming when it comes to motorcycles - totally ignoring that it is very much a team sport, that without the bike under him, he ain't going anywhere - and now that he has had free rein over Ducait's R&D budget for more than a year, he should be back at the sharp end, therefore it HAS to be that the engineering team are doing it wrong and that Hayden's abilities are an aberration.
What do I know? I just think he can't ride the Ducati.
If he had the Honda underneath him it would be a four-way battle for the lead at every race. He isn't washed up, but he is finding those big-headed chickens have come home to roost... he needs to suck it up and carry on. Behaving like a spoilt six-year-old is not the right thing to do, IMO.
