What's your point? That Brawn was only any good when faced with major regulation changes? If so, how do you explain his constant success at Bennetton and Ferrari, when the rules were stable by comparison? And his slump in form once Mercedes came on-board and the sport again had stable rules? 2010 can be excused, given the financial problems the team had in 2009; they were pretty much relying on race-by-race sponsor deals to get to the next Grand Prix, and when Barrichello crashed qualifying for the Singapore Grand Prix, he took the team's only spare chassis, so from that point on, a single race-ending mistake could have cost Button the title, which had had to win in a car that had taken part in every single pre-season test, free practice session, qualifying period and race; it literally had tens of thousands of kilometres on it before he was even in a position to win the title, while the Red Bull drivers got brand-new cars to chase him down.
