Losers in their past seven Finals appearances, the aging 1971-1972 Lakers seemed destined for another playoff bust.

But with Hall of Famers Jerry West, Gail Goodrich, and Wilt Chamberlain manning the fort, these Lakers went on a 33-0 tear en route to an explosive 69-13 season (The NBA record for most wins in a regular season until the Chicago Bulls broke it with its 72-10 win-loss card in 1996) and finally an NBA championship.

Considered the greatest female tennis player of all time, Navratilova won a combined 58 Grand Slam titles (singles, doubles, and mixed), which included a record six consecutive Wimbledon single titles from 1982 to 1987. Her greatest feat, though, would have to be her 74-match winning streak, the longest of any player in Tennis' Open era. The streak saw her win 13 titles in a row, including the French and US Opens and the Wimbledon. Just how good was she during the almost year-long streak? She only dropped seven sets of the 155 she played!
