But they did have Rindt, Rodriguez, Surtees, Siffert and briefly Amon.
Jochen was without doubt Cooper's most successful driver over the whole of 1966 and, had he been luckier he might have won a GP or two that year. But even his most ardent fans wouldn't claim Jochen was a car developer, which is what the Cooper needed in 1966. Surtees took a 1st, 2nd and 3rd and could perhaps have developed the car but jumped ship to Honda ...
Pedro took a lucky win in South Africa, when everything else blew up, but it should be remembered that he almost certainly wouldn't have won if John Love's old Cooper hadn't stopped for fuel - the 1967 Cooper was slow, but reliable.
Siffert's RRCW car was even less competitive than the works cars and I'm sure Rob heaved a mighty sigh of relief when the Lotus 49 rolled into his garage in 1968!
And
very briefly Amon ... I'd actually forgotten Chris had driven the Cooper, but I suppose we can rely on you to remind us about all things Amon, Keir: at least he had a car to drive, which is more than Bruce could provide at the time. I suspect the effort of running three cars was too much for Cooper, but for some reason they kept on doing it .... starting money perhaps?
John Cooper was a revolutionary, but when he looked around, the revolution had passed him by.
And the revolution was monocoques ....
