Hamilton is the GOAT. Check his former teammates, engineers and other driver interviews to confirm. Nobody can best him over one lap, he's one of the best in the wet and he's made the most of his Mercedes seat (combination of good luck and good choice).
Very rarely do you have engineers saying "that time is not in the car, no idea how he did that".
We'd all love to see them race in the same car but that's not the way the game works. The best drivers stay and with a bit of luck find their way to the best seat. He's made the most of it.
Rate Kimi but Hamilton lost that debut title in the pits in Shanghai.
Imagine beating Fernando Alonso in your rookie season.
