He really isn't.
He is faster than DC, which counts for a lot. Can't see him being completely shaded by better teammates in the way that DC was.
I increasingly agree that he seems to lack that doggedness that defines guys like Hamilton, Verstappen and Alonso who maximise every scrap of an opportunity.
That said despite his experience, he is still only 24. Maybe there's still some development to come. McLaren needs to stop allowing him to make strategy calls, that much is for certain.
