Dennis Keith Rodman (born May 13, 1961) is a retired American Hall of Fame professional basketball player of the National Basketball Association's (NBA) Detroit Pistons, San Antonio Spurs, Chicago Bulls, Los Angeles Lakers and Dallas Mavericks. Born in Trenton, New Jersey, he was nicknamed "The Worm" and was known for his fierce defensive and rebounding abilities. Playing small forward in his early years before becoming a power forward, Rodman earned NBA All-Defensive First Team honors seven times and was voted NBA Defensive Player of the Year twice. He also led the NBA in rebounds per game for a record seven consecutive years and won five NBA championships (1989, 1990, 1996, 1997, 1998). His biography at NBA.com states that he is "arguably the best rebounding forward in NBA history". On April 1, 2011, the Pistons retired Rodman's #10 jersey. Later that same year, Rodman was inducted into the Naismith Memorial Basketball Hall of Fame. Rodman experienced an unhappy childhood and was shy and introverted in his early years. After aborting a suicide attempt in 1993, he reinvented himself as a "bad boy" and became notorious for numerous controversial antics.
