In fairness, Hammer, Brawn GP didn't have the development during the year that everybody else did. Sure, they started with a car 1.5 seconds faster, but by the 4th race the jig was up. Everybody else was introducing their own blown diffusers and negated that advantage. That's why Jenson almost lost it: He finished the year in the same car he stated with while everybody else got better and better cars.
