There is no doubt that Jimmy was no.1 in 1978. He was also no.1 in 1977, yes that's right. People confuse No.1 ranking with "the best player". In 1977 Jimmy got to 2 GS finals, he didn't play the other 2, and he won the WCT and Masters. He had the best average results for the year, not head to head, not who was the best player, but he was ranked no.1, check the record books. (Awaits people talking about titles, head to head records, and who was the best player etc, none of which is relevant to the No.1 ranking). Anyway back to 1978, it was definitely Jimmy Connors!
