I don't think there will be anyone who can legitimately challenge Pecco and Marc.
The only one would be Martin. Apparently Aprilia has a good base (Ogura and Bezz did a good job in this first GP). Martin would probably get a podium if he were in the Japanese's place.
Of course, technically Quartararo and Acosta have the ability to do so, but they don't have the equipment to compete.
Alex was a "surprise", I mean, he has the tools. But you never look at him as a favorite. I believe he can be a constant presence on the podium and take some points off the official ones.
Morbidelli should be that person, because he is the most experienced in GP24 among the satelites Desmo.
We'll see if DiGia can keep up too, he has an updated bike, but he's physically inferior.
Aldeguer doesn't enter the equation.
Anyway, believing that PB63 and MM93 will monopolize the victories, I made a chart where I think each one will finish ahead of the other in the season. And it's very balanced.
What do you think?
