It's certainly true that, if Hamilton had been willing to demand contractual number twos as is standard practice at the sharp end of the grid, then he'd have at least two more championships and many more race wins. What Schumacher and Hamilton do share though, is a willingness to constantly work harder and improve more. That's not universal by any means, even on the F1 grid. It makes sense given all the obstacles Hamilton's background would have presented. He needed to be better because he had neither the money, the connections or the look to make it easy.
We'll see who in the new crop has that same iron discipline.
Verstappen? Maybe he turned a corner last year or, perhaps, he's simply not been put under the necessary pressure to reveal his flaws again. He's driven a great season so far.
Leclerc? Has also been great. Second season in F1 he beat his formal team number one, a four time WDC. This season he's driven excellently, dragging that dog of a car to some great finishes. Styria was clumsy, a worrying brainfade. It'll be interesting to see if he can eliminate such moments. Probably my driver of the season so far.
Norris, Ocon, Russell? We'll have to wait and see.
Perhaps the topic for next year's thread should be "Why no one under the age of 25 will win in 2021"?
