I think it's last chance saloon really. What I hope is that Audi, and the contract backed to Valentino has a clause that states they'll technically follow his, and his crews direction, anything else and he has the freedom to walk midseason.
In all honesty, this should have been sorted a LONG time ago. At present, MotoGP is about making a bike that can go as fast as possible on THE spec tyre.
The bike doesn't exploit the qualities of the tyre, not does it exploit the qualities and skills that most the riders possess.
IF the attitude towards riders in Corse changes, and lets face it, that's exactly what it needs now, then they might be able to start challenging near the front.
No one wins a championship by luck, but several unlikely events can line up to help. In 2007 Ducati only won that championship because they hired Casey, and he wasn't even at the top of their list. Casey without doubt deserved it that year. Ducati (look at where his teammate came) perhaps didn't deserve it as much.
They've 10 world GP titles between their current Factory rider lineup, and they've 15+ with Burgess at the helm, the guys know how to win, they just need the tools.
I think the best thing Audi can do is 1) make budget available 2) Tell Big Phil/The Ducati board to allow 100% direction from the race team and 3) perhaps assist in engine/electronics where possible - this is something they have vast experience in, some of this can be translated to bikes.
I'd agree with Pagik as well, words are fine, but if Rossi doesn't see actual action, then I think that's it.
By Laguna, I'd expect the direction of the bike to start going in a direction that allows Rossi to ride how he rides, once they start in that direction, I think he'll be ok.
