JCF had a beautiful game and a couple of fantastic years at the top of the clay court tree. However, I can't name another top player who played as badly as he did when he was having an off day. Finding a way to win when you're not at your best is something we see in all the greats. Sadly, when JCF wasn't at his best, he wasn't good at all.
Talking about 'forgotten' champs - I sat courtside with about 12 other people for one of Albert Costa's AO matches. Also a sad audience for a former clay court king and grand slam champion.
