Richard Francis Dennis Barry III (born March 28, 1944) is an American retired professional basketball player who played in both the American Basketball Association (ABA) and National Basketball Association (NBA). Named one of the 50 Greatest Players in history by the NBA in 1996, Barry is the only player to lead the National Collegiate Athletic Association (NCAA), ABA and NBA in scoring for an individual season. He was known for his unorthodox but effective underhand free throw shooting technique, and at the time of his retirement in 1980, his .900 free throw percentage ranked first in NBA history. In 1987, Barry was inducted into the Naismith Memorial Basketball Hall of Fame.

In Barry's first season in the NBA with the Warriors, the team improved from 17 to 35 victories. In the All-Star Game one season later, Barry erupted for 38 points as the West team stunned the East squad, which featured Wilt Chamberlain, Oscar Robertson, Bill Russell and head coach Red Auerbach among other all-time greats. Later that season, Barry and company extended the mighty Philadelphia 76ers to six highly competitive games in the NBA Finals, something that Russell and the Boston Celtics could not do in the Eastern Conference playoffs. That 76ers team is considered to be one of the greatest in basketball history.  Nicknamed the "Miami Greyhound" by longtime San Francisco-area broadcaster Bill King because of his slender physical build and remarkable quickness and instincts, the 6'7" Barry won the NBA Rookie of the Year Award after averaging 25.7 points and 10.6 rebounds per game in the 1965-66 season. The following year, he won the 1967 NBA All-Star Game MVP award with a 38-point outburst and led the NBA in scoring with a 35.6 point per game average -- which still ranks as the eighth- highest output in league annals. Teamed with star center Nate Thurmond in San Francisco, Barry helped take the Warriors to the 1967 NBA Finals, which they lost to the Philadelphia 76ers in six games. Including a 55-point outburst in Game 3, Barry averaged 40.8 points per game in the series, an NBA Finals record that stood for three decades.  Upset that he was not paid incentive monies that he believed due from Warriors owner Franklin Mieuli, Barry jumped to the ABA's Oakland Oaks, who offered him a lucrative contract and the chance to play for Bruce Hale, his then father-in-law. The three-year contract offer from Pat Boone, the singer and team owner, was estimated to be worth $500,000, with Barry saying "the offer Oakland made me was one I simply couldn't turn down" and that it would make him one of basketball's highest-paid players. The courts ordered Barry to sit out the 1967-68 season before he starred in the ABA, upholding the validity of the reserve clause in his contract. He preceded St. Louis Cardinals' outfielder Curt Flood, whose better-known challenge to the reserve clause went all the way to the U.S. Supreme Court, by two years as the first American major-league professional athlete to bring a court action against it. The ensuing negative publicity cast Barry in a negative light, portraying him as selfish and money-hungry. However, many NBA players at the time were looking at jumping to the ABA for more lucrative contracts. Barry would star in the ABA, twice averaging more than 30 points per game.
