I thought the same watching the race, with no particular rancour against him currently, what is the point of him racing for a position in the lower reaches of the top 10 ?. Maybe MM is so good he would be destroying prime Rossi and prime Doohan, but 40 year old Rossi and an aging injury plagued Jorge on the wrong bike are not providing any competition however good they may once have been, and I don’t think lightning is going to strike twice for Dovi again in terms of actually contending although he probably has more high finishes in the points other than first in him. Petrucci and Miller don’t look very likely either. Maybe Vinales’ early races for Yamaha were something of a fluke as well, it is hard to think he is being less than fully backed by Yamaha now after I tended to blame favouritism towards Rossi for his fade out in that first year. FQ and Rins at least look to have good pace, those guys and maybe Morbidelli seem to be the future in the current field.
Uncle Carmelo may still be keen though, and Yamaha struggled for sponsorship while Valentino was at Ducati, but him transitioning to be the Yamaha team principal as you imply might address most of that. I guess being flogged by MM as a team manager may lack appeal for him as well.
