Stoner was never going to ride into his thirties because of injuries, and I doubt MM will, he will need to surpass Rossi in his twenties imo.
Whatever my opinion of some aspects of Rossi as a gp bike rider, his freedom from injuries which does largely come down to his skill and riding style and physical resilience/toughness extending into his late thirties is quite remarkable. I leave out mental toughness because while Rossi has that to a remarkable degree, even so I believe MM has him covered and is unlikely to lose that.
I wouldn't be surprised to see MM riding in his 30s. I think that's become the new normal. In theory, an injury free Marquez could be reasonably expected to surpass Rossi's golden years achievements, if only because he started training at an early age, which Rossi did not. It should make it easier to maintain good muscle tone, and body weight as he ages. Also a stronger immune system. It's really a question of whether he'll continue to be motivated.
