If Cal has an offer on the table from Ducati then good for him
But he's got a lot more work to do to justify a works Yamaha ride, and Spies has a lot more poor performances to put in before losing his, not to mention the Dovi factor. I don't think Cal would be a miracle worker at Corse, but I do believe he would acquit himself better than the incumbent pilots.
I'd love to see Corse give a few young boys try outs. Pol Espargaro and Scott Redding in particular. Marquez could make that latin girl dance a fiery Tango but he's kind of accounted for.
Given that Ducati have intimated they want to keep both their current riders, yet supposedly at the same time they're offering Cal a contract, then we have pork pie city.
Hayden is going nowhere from his perspective - it's Corse, a CRT, WSBK or retirement for him.
Rossi is completely fed up with his own inability to adapt and ride the D16 in the manner he knows it deserves, and wants out. He's clinging to hope against hope that somehow he can worm his way onto a factory Japanese seat (he'd better be praying M1 because as it stands that RCV would bite his scrawny arse just as hard as the D16). I really can't see any Yamaha availability for him across the four seats on offer. Tech3 aren't going to want to upset a well working machine to accommodate Rossi and his entourage. Factory M1 next to Lorenzo? Oh that would be delicious just for the humble pie! But this remains highly unlikely.
Rossi on a satellite spec RCV sounds the most likely course of action. Would HRC give him a factory spec? On performance he certainly doesn't justify it. But IF he can bring the money then I would think HRC would be more than confident of DP & MM whipping yellow butt.
