To be fair, for all the cast-asides along the way, they got it right with Max. I guess it depends on what they consider an acceptable ratio of success-to-failure.
Yes and no.
They got it right with Adrian Newey managing to think seven ways of sideways on the technical front, although it's common knowledge that like Ferrari a handful of years ago (the whole fuel flow palaver - we now don't get the fuel flow stats, kind of funny, that...) the car isn't 100% legal but they've got away with it. Well, ish. They've also benefitted massively from the incompetence of the race directors / race officials making up rules on a whim.
But they've got it massively wrong by building the team around one driver. They've not learned from the mistakes of history.
And don't forget the eyewatering amounts of money thrown at Max since he was about 4 years old. He's always had the best of everything, which actually masks how good a driver actually is. And he's been greased through the system without having to work for is. This season, we've seen that when he doesn't have the best car, he struggles with both speed and racecraft. And with Newey leaving and less prize money to funnel into the upcoming cars, this is something the team may come to regret.
You'd think they'd have learned from the Vettel years...
Well, those who ignore the mistakes of history are condemned to repeat them.
