A truly great driver will get the best out of any car.
if thats true, than schumacher would be 8 or 9 time champion. But he clearly had struggles with the changes after his 7th Title.
Hamilton would have won 2009, 2010 and 2012(?)
And 2009 tells us a great deal about WCC and bad driving the next year. Button DESTROYED Hamilton (because he had a jet engine, but whatever, hamilton also lost against the redbulls and wasnt even in the points over half the races when he finished.) like Hamilton now destroys Vettel.
So, how can such a great driver go from WCC to fifth? And only win the WCC again (maybe) when he has a car that can go from 20th to 2nd in half a race?
Vettel proved himself in 2010 ind 2012. I dont think Hamilton would have had the nerves to win 2012 if he was in that Position.
We dont really know what is going on with Vettel this year. Maybe he is not motivated after 4 WCC, he struggles with the new Cars or Ricciardo is really just faster than Vettel.
We will get an Understanding in 1 to 3 years, when Vettel had driven for Ferrari. And the red Bull Caroussel allready dumped Ricciardo because every generation of Redbull yung Driver Program is faster then the previous and Kvyat and Verstappen are driving 2017 in the Red Bull *shrug*
It just could be, that Red Bull is no place for a 4 time World Champion. When Vettels departure from RB was announced, many german news sites reported, that this was no surprise, because Vettel didnt felt or received the support he needed. And he wasnt OK with some Staff changes (firings), or even the private live of Horner (duming the wife). I dont know about the Horner thing, but if you are not happy with the current ongoings in your team and you dont have a shot at the WCC.....
A World Champion like Vettel expects more support from a Team when he struggles with a new Design of the car and shouldnt have to be worried about a "Ricciardo is faster than you, please let him past".
Maybe Red Bull really has this cutthroat mentality, where only the team matters and not the driver. So every new, young, promising driver is a thorn in the side of the established driver. Red Bull would not be a desired team for World Champions. They expect all the Support from their team, even from their teammate. Alonso would not be happy with driving for Red Bull, if every new young driver could potentially be his rival for the WCC. Maybe he wouldnt even get a drive in Red Bull because he would want a Number 1 clausel in his contract.
Or Red Bull didnt car about Vettel anymore because they knew he would leave them sooner or later, so they gave Ricciardo more support, because thats their new horse that they are grooming, before a new driver comes along.
