Tennis fans of the 1980s saw the rivalry as “Iceman vs. the Volcano,” with the implacable Swedish sex symbol Bjorn Borg—winner of five consecutive Wimbledon tournaments—facing temperamental American upstart John McEnroe in an epic 1980 final that forms the pivotal center for the second episode of a terrific sports docuseries. They would meet again in 1981, in a match where McEnroe literally bites his lip to keep his temper in check, ruffling Borg’s composure so thoroughly it would change the course of his career. Both men reflect on their rivalry, with McEnroe stating, “I believe I was misunderstood” when he became the first player ever fined at the tournament for bad behavior. The irony being that he is now the sport’s elder statesman as a leading TV commentator.
