I admire your adoration of Schumacher. But, just for fun, I would suggest you to look for instance at Prost's career, his results, his cars and his teammates.
Taking with some historical perspective one could say that Prost was the biggest because of the rivals he had. But people keep saying how great was Senna and at the time underestimating Prost´s qualities.
And I am a huge MSC fan but I think people have been quite unfair with Prost.
I mentioned Prost to show the difference in eras. I could of mentioned Piquet.
With Prost, if he wasn't partnered with WC all of the time at the furious dominant McLaren, he would have been champion from 1984 up to 1991.
But then Senna happened. Car control not seen since Jim Clark.
Schumacher had it reletive easy. The great of the era before just left or died, no dominant drivers at the beginning of his career and that gave him together with Brawn the opertunaty to make one of the most dominant teams like McLaren the years before.
If Brawn had the same way with Schumacher as Dennis did with Prost, he would have been partnered with Alonso and/or Hakkinen instead of Barichello.
Unlike Piquet, Prost and Lauda, Schumacher never had anything to fear from within the team. Not from managers or drivers. That's not a point of criticism but one of things why he was so successful. Building/being part of a team with one single focus.
