His technique – unconventional yet lethal.
Barry was known as a scorer and piled up 13% of his career NBA points (3,818) on free throws, which he shot at a 89.3% clip in his NBA career. He was known for his accuracy there and also his form, too, where he used an outdated-yet-accurate underhand style few players have tried since.
In his first two NBA seasons, Barry was a scoring force. As a rookie, he averaged 25.7 ppg (fourth in the NBA) en route to Rookie of the Year, All-NBA and All-Star honors as the Warriors' win total improved by 18. He followed that up in 1966-67 by averaging a league-best 35.6 ppg, was named an All-Star and All-NBA First Team selection again.
Barry led the Warriors to The Finals in 1967 and averaged 40.8 ppg, including a 55-point effort in Game 3 of the series and a 44-point performance in the Game 6 series loss to the Philadelphia 76ers. That season, Barry also was an All-Star once again and earned his lone All-Star Game MVP award after scoring 38 points.
After two successful seasons in the NBA, Barry went to the ABA for four seasons and also found immense success. He led the Oakland Oaks -- which became the Washington Capitols in 1969-70 -- to the 1969 ABA title while winning the ABA scoring crown that season, too. He also played for the New York Nets, leading them to an ABA finals berth in 1972, which they lost 4-2 to the Indiana Pacers.
A court decision before the 1972-73 season forced Barry to return to the Warriors, where he spent the next six season and led Golden State to four playoff berths. Over the next eight seasons, Barry would collect seven All-NBA First Team honors, six free throw percentage titles and ranked No. 2 in 3-pointers made in the 1979-80 season (the NBA's first season with the 3-point line).
Barry's landmark season came in 1974-75, when he averaged 30.6 ppg, 2.8 spg and 6.2 apg to power Golden State to a 48-34 finish. The Warriors ousted the Chicago Bulls in Game 7 of the West finals, then stunned the NBA world when they upset the heavily-favored Washington Bullets in the 1975 Finals. Barry ran wild in that Finals sweep, averaging 29.5 ppg, 4.0 rpg and 5.0 apg overall en route to earning Finals MVP honors.
While Barry's role diminished in his final two seasons with the Houston Rockets, he led the league in free-throw percentage (94.7% in 1978-79 and 93.5% in 1979-80). Upon his retirement in 1980, he had a career scoring average of 23.2 ppg and was the NBA's most accurate free-throw shooter ever.
