In his 1979 autobiography, Jack Kramer had already included Borg in his list of the 21 greatest players of all time.[citation needed] And in 2003, Bud Collins chose Borg as one of his top-five male players of all time.[6] In 1983, Fred Perry listed his greatest male players of all time and listed them in two categories, before World War 2 and after. Perry's modern best behind Laver: "Borg, McEnroe, Connors, Hoad, Jack Kramer, John Newcombe, Ken Rosewall, Manuel Santana".[7] In 1988, a panel consisting of Bud Collins, Cliff Drysdale, and Butch Buchholz ranked their top five male tennis players of all time. Buchholz and Drysdale both listed Borg number two on their lists, behind Rod Laver. Collins listed Borg number five behind Laver, McEnroe, Rosewall, and Gonzales.[8]
