RickD. I am sure he had input in the Brawn development but I will be amazed if he thought up the double diffuser. He has certainly galvanised the team around him at McLaren and this will probably continue with more pace now that Lewis is out of the way. Whether his input will lift the team or not is a different matter and we are yet to find out. The talk mid-season, in some factions, this year was about his input somewhat hampering the team. Many said they got a bit lost trying to bring the car to him and his narrow operating window for extraction of peak performance whilst Hamilton was able to move towards the car and extract the performance from whatever he was given.
