We talk about being a great driver?What do you need for a great season? Beating Verstappen, Ghiotto, Rosenqvist, Blomqvist, Giovinazzi and Auer is not enough?
You need more than a season with a good car which proves nothing compare to the rest of his career which has been very discutable.
Of course that's the point for all drivers.
You are looking for a good driver? Give him a bad car and check what he is capable, that's the only way to make an opinion. If he is capable to have results, you probably have a good driver.
That's my point of view.
Ocon has proved nothing except that he was able to win when he had the best car of a championship and that he has a strong political support.
It does not make him a great driver.
