IMO the drivers play an important part in the feedback they give the engineers for them to work with, unfortunately in todays aerodinamics in F1 cars and years to year changing regulations, sometimes a single element gives such a huge advantage that everything else in shadowed, like a rear diffuser or a flexible front wing, but in the "long run" a good lead driver is necesary to hold the team together and in the same direction, and also help development of the car, for a good run like Schumacher had, everything needs to click together.
