Duke / BMW
Seems a little like the situ some time back with BMW and Corser/Xaus
They had one old guy, clearly a great rider and development expert, employed to make thier bike a winner, and a crazy spaniard to win the races - Duke have the old boy/Dev guy in rossi and have had thier share of young wild things in Melandri/Hayen ect to win - but to no avail, the same as BMW.
So BMW swapped out thier oldboy and wildone for two fast racers who could make a difference through thier adaptability, experience and big bollox. Duke need to do the same, get two younger guys who have no preconceptions and have talent to make the bike work by adpating thier style as much as adpatation of the bike (if duke would allow...).
Trouble is, who do you really have that fits the bill - Dovi, Cal, Spies, a Moto2 guy like Iannone or Redding or a WSBK guy such as Rea or Haslam? and who wants the risk of the career killing duke..?
So back on topic, dont do it Cal
If the Factory Yam offer is there then go for it, if Duke choose someone else it will be Spies which means you need, absolutely must beat your teammate to get the M1 ride.
