You think an F1 team can be top, just because of 1 man?
Do you really believe that?
Where would Ferrari have been without Michael Schumacher? Yes, they had an incredible array of talent at that team for the period he was driving for them - but they were there because Michael was there.
Same goes for Red Bull. Yes, Vettel is an incredibly talented driver. Yes, there are many people working very hard at that team to bring home trophies. Where would they be without Adrian Newey there? Upper midfield, IMO. Newey's first two cars for the team were hamstrung by cooling problems - the RB3 - and a lack of power - the RB4, which was the last RBR car to run before Renault were allowed to ignore the engine freeze and catch back up. His third car was probably the best car on the 2009 grid - the McLaren and Ferrari were awful cars elevated by inspired driving, the Brawn was a starting money special that had no right to be as quick as it was early in the year, the BMW was useless, the Renault not much better. And he's not built a duff one since. He does occasionally get it a bit wrong (*cough* McLaren MP4-18 *cough*)¹, but more often than not he builds 'em right.
