10. Lakers Win 33 Straight

Date: 11/5/1972-1/7/1972

Two months is a long time in an NBA season. The travel and stress is enough to wear down the best of teams. Two months without a loss in the NBA is absolutely unimaginable. Yet despite Elgin Baylor's retirement after just eight games, the Lakers did just that in 1972, defeating the Baltimore Bullets on November 5th and not losing until January 7th in Milwaukee. Their 33 games are the longest winning streak in any pro sport and will likely never be broken.
