im a fan, but arguably the Hulk wasnt delivering either.
Perez is a pay driver as well and, if memory serves, he made more of a mark at Force India then Hulk did and while Hulk probably fared better vs Perez then Stroll did against Perez this season, overall both got beaten fairly regularly by Perez.
that of course has little to do with whether or not Stroll still deserves a seat though!
