Well, there is a big if. Hamilton challenged Alonso in his debut year, Perez is no Alonso. Verstappen challenged immidiately Ricciardo, Perez is no Ricciardo either. Button beat also Perez with clear margin. Ocon seems to be whiner too so I can´t see any reason, but bigger marketability to french speaking countries that would come with him. Young age of course is an advantage too...but Ocon following Hamilton as their leading driver seems utopistic, especially when there are guys like Verstappen available sooner or later
the other thing ignored is that the strong thing Perez had over Ocon was tyre management, so it seems that was not, at that time, Ocon's asset. His speed was great.
But Bottas has similar struggles. Why people assume Ocon will be better at tyre management vs Lewis than he was vs Perez is what puzzles me
