Question: Which former president of the of the Indiana Pacers organization helped to turn around the Boston Celtics 1979-80 season?
Context: Peter Dinwiddie is a front office executive in the NBA for the Indiana Pacers.  He is currently Senior Vice President of Basketball Operations and has been with the Pacers organization since 2006.  He was named to the Indianapolis Business Journal's Forty Under 40 list in 2017, which is composed of individuals who have achieved success both in their jobs and in the community.  During his tenure as Vice President, he has worked closely with Larry Bird and Donnie Walsh and the Pacers have reached the Eastern Conference Finals and won the Central Division each twice. The 2002–03 NBA season was the 57th season for the Boston Celtics in the National Basketball Association.  During the offseason, the Celtics acquired Vin Baker from the Seattle SuperSonics.  The Celtics posted a six-game winning streak after losing their first two games, and got off to a solid 16–7 start.  However, they lost six straight games in March, and finished third in the Atlantic Division with a 44–38 record.  The team made the playoffs for the second time with team captain Paul Pierce, but this time as the #6 seed in the Eastern Conference.  Pierce and Antoine Walker were both selected for the 2003 NBA All-Star Game.  After defeating the 3rd-seeded Indiana Pacers four games to two in the first round, they were unable to stop the New Jersey Nets as they were swept in four straight Conference Semifinal games.  This was also Walker's final season with the Celtics, as he was traded along with Tony Delk to the Dallas Mavericks the following offseason.  He would return to Boston midway during the 2004–05 season. Jermaine Lee O'Neal (born October 13, 1978) is an American former professional basketball player.  The 6 ft 11 in (2.11 m), 255 lb (115 kg) forward–center had a successful high school career and declared his eligibility for the 1996 NBA draft straight out of high school.  He was selected by the Portland Trail Blazers with the 17th overall pick, but O'Neal was unable to break into the first team in Portland and was traded to the Indiana Pacers in 2000.  In his eight seasons with the club, he was voted an NBA All-Star six times, made the All-NBA teams three times, and was voted the NBA Most Improved Player in the 2001–02 season.  He also helped Indiana reach the NBA Playoffs six times, including the Conference Finals in the 2003–04 season.  He was traded to the Toronto Raptors before the 2008–09 season began, and traded to the Miami Heat midway through the same season.  O'Neal joined the Boston Celtics prior to the 2010–11 season.  In 2012, he signed with the Suns, and in the offseason of 2013, he signed with the Warriors. Larry Joe Bird (born December 7, 1956) is an American professional basketball executive, former coach and former player, most recently serving as president of the Indiana Pacers in the National Basketball Association (NBA).  Since retiring as a player for the Boston Celtics, he was a mainstay in the Indiana Pacers organization, but stepped down from the position of president following the first-round of the 2017 Eastern Conference playoffs. Joseph Donald "Donnie" Walsh, Jr. (born March 1, 1941) is a front office adviser of the Indiana Pacers and a former professional basketball coach.  He is also the former President of Basketball Operations for the New York Knicks and Indiana Pacers. The 1979/80 season was the Jazz sixth season in the NBA and its first in Utah.  The Jazz averaged 102.4 points per game (ranked 22 in NBA) while allowing an average of 108.4 points per game (ranked 10th in NBA).  The attendance was 320,649 (ranked 21st in NBA).  The attendance figure was worse than the last season in New Orleans, where the club had an attendance of 364,205 (ranked 18th in NBA).  In addition, the Jazz move from the Central Division to the Midwest Division (with the Indiana Pacers replacing them). William Quinn Buckner (born August 20, 1954) is an American former professional basketball player and coach.  He played collegiate basketball for the Indiana University Hoosiers, and was selected by the Milwaukee Bucks with the 7th pick of the 1976 NBA draft.  He had a ten-year NBA career for three different teams (the Bucks, the Boston Celtics, and the Indiana Pacers).  In 1984, he won an NBA title with the Celtics. The 1946–47 Boston Celtics season was the first season of the Boston Celtics in the Basketball Association of America (BAA/NBA).  Walter A. Brown was the man who was responsible for starting the franchise.  On an early June day in 1946, Brown, who operated the Boston Garden arena and was part of the National Hockey League's Boston Bruins, was the driving force behind the Basketball Association of America and the Celtics birth.  After considering several team names, including Whirlwinds, Unicorns and Olympics, Brown opted for Celtics.  He hoped to grab the attention of Boston's large Irish American population.  John Davis "Honey" Russell was hired as the first Celtics coach, and the team soon began its inaugural season, losing its first game 59–53 to the Providence Steamrollers.  Although the Celtics would eventually become the signature franchise of the NBA, the club had a lacklustre first season as they started with 0 wins and 5 losses.  The Celtics won their first game of the season against the Toronto Huskies. The 1990–91 NBA season was the Pacers' 15th season in the National Basketball Association, and 24th season as a franchise.  In the offseason, the Pacers signed free agent Michael Williams.  The Pacers would get off to a slow start with a 9–16 record, as head coach Dick Versace was fired and replaced with Bob Hill.  Under Hill, the Pacers played around .500 again finishing fifth in the Central Division with a 41–41 record.  Reggie Miller continued to lead them in scoring with 22.6 points per game.  Detlef Schrempf was named Sixth Man of The Year averaging 16.1 points per game off the bench.  A heartbreaking five-game defeat to Larry Bird and the Boston Celtics kept the Pacers from advancing in the playoffs.  In the series, the Pacers came close to taking the final two games, but lost by just three points in Game 5 at the Boston Garden. The 1979–80 Boston Celtics season was the 34th season of the Boston Celtics in the National Basketball Association (NBA).  Bolstered by the play of Rookie Larry Bird, the Celtics improved by 32 wins from the previous year (at the time the largest turnaround in NBA History).
Answer: Larry Bird
