Without tennis coaches, a load of financial backing and top class facilities Murray would probably be useless, same with any footballer, boxer etc
Hmm. Let me think how to word this.
The F1 team are active during the race, all the way through, every second. They are talking to the drivers constantly giving feedback on the car, weather, everyones position. They make the decision on pitstops, tyre and tactics. The driver is no more important than the car, and some would say less so.
They interpret the rules and rebuild cars everytime the rules change to get as much as they can from the rules.
The team behind F1 is huge. The cost for just running the team for a season is in excess of 150 million dollars. Thats running the team, nogt all the innovation that goes on to produce the cars. The innovations that come from F1 make it into road cars.
There is a team behind every sportsman or woman, but the performer ultimately goes out on their own 1v1, head to head, mano et mano, face to face... I am running out of cliches now, but you get my point. In F1 the victories belong to the team, some of whom aint even at the track and never attend.
