I was watching some old VHS tapes of 1990's GP's and it got me thinking about the best defensive drivers. Credit always goes to the "best" (usually the fastest) driver, or the grestest overtaking move, but rarely does the skill of holding off a superior car/driver get much of a mention. (Aside from the obvious Gilles battle)

I'd like to nominate HH Frentzen as a top notch defensive driver. Driving for Sauber he was often filled to the brim on a 1 stopper with a queue of 2 or 3 stoppers behind him. Yet he always seemed to place the car beautifully and was rarely passed.

Thoughts?
