Jacques Villeneuve was a great champion and his title is well deserved. He beat Schumacher and Ferrari while they were on the ascendancy. Plus he's one of the few guys who constantly tried to go flat from La Source to Les Combes back when that was still a very hard thing to do in an F1 car, so he gets the mad dog stamp of approval in my books. Plus he won the Indy 500. Come on.
Frank Williams was a sportsman first and an engineer second, while Patrick Head was an engineer first and a sportsman second. Both had amazing business nous. Perfect combination to run a team. They out-Ron Dennis'd Ron Dennis in the early 90s, and it took Dennis poaching Adrian Newey to turn the tide, when McLaren could no longer rely on the immense horsepower and reliability of both the turbo and atmo Honda engines of that era.
