I think the best example is Fisico.
He’s a clear case of “wrong place at wrong time”. He was a Jordan, did well, but left just before they became winners. He went to Benetton, which was already going down with those outdated Mecachrome engines. Stayed there and left just as Renault bought took over the team, going back to Jordan which had already passed their golden era.
Went to Sauber, did good, then Renault. His biggest chance, a championship winning car. But he was already 32 by then. And he had a much much better team mate.
Frentzen did better with Williams than Fisi with Renault. Im a Fisi fan myself and I reckon i was extremely dissapointed with his performances most of the time!
