i think Mclaren slide is due to the areo guys all leaving in one big hit... If you compare the rate of development from the 2005 car to the 2006 car its obvious that they are not making the big steps forward like they were last year.
Coulthards impact on the car couldnt be too significant as he was always the second driver to Mika and then got out done by Kimi. You would think that Maclaren would build a car to suit the needs of there no.1 guy, not no.2... Personally i think the fact that newey and DC follow each other around is just a strange co-inkidink.
If red bull keeps newey and a dood driver like DC, and then gets supplied Renault engines... they're gonna be dangerous
