full_context: Document 1: 2003–04 Indiana Pacers season: The 2003–04 NBA season was the Pacers' 28th season in the National Basketball Association, and 37th season as a franchise. During the offseason, former Pacers head coach Larry Bird was named President of Basketball Operations. One of Bird's first moves in his new position was to fire head coach Isiah Thomas, after Thomas had led the Pacers to first-round playoff exits for three consecutive years. The defensive-minded Rick Carlisle, former head coach of the Detroit Pistons, was announced as Thomas' replacement. Also during the offseason, the Pacers acquired Scot Pollard from the Sacramento Kings in a three-team trade and signed free agent Kenny Anderson.

Document 3: Larry Bird: 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).

Document 4: 1978–79 Boston Celtics season: The 1978–79 Boston Celtics season was the 33rd season of the Boston Celtics in the National Basketball Association (NBA). It was the worst record of any Celtics team that played between 1950 and 1996.
Document 5: 1993–94 Boston Celtics season: The 1993–94 NBA season was the 48th season for the Boston Celtics in the National Basketball Association. This season marked the first since 1978–79 that the Celtics failed to qualify for the NBA Playoffs (a streak of 14 seasons), finishing fifth in the Atlantic Division with a 32–50 record. Tragedy struck the team prior to the season when star forward and team captain Reggie Lewis died of cardiac arrest during practice. The absence of Lewis, and the retirements over the previous two seasons of Larry Bird and Kevin McHale contributed to the poor season. The Celtics had a 7-game winning streak in January, but also had a winless month in February where they suffered a 13-game losing streak. Rookie Dino Radja was named to the All-Rookie Second Team. Following the season, longtime Celtics center Robert Parish signed as an unrestricted free agent with the Charlotte Hornets, and Kevin Gamble signed with the Miami Heat.
Document 6: 1980 NBA draft: The 1980 NBA draft was the 34th annual draft of the National Basketball Association (NBA). The draft was held on June 10, 1980, before the 1980–81 season. In this draft, 23 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip. The Boston Celtics, who obtained the Detroit Pistons' first-round pick in a trade, won the coin flip and were awarded the first overall pick, while the Utah Jazz were awarded the second pick. The Celtics then traded the first pick to the Golden State Warriors before the draft. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. An expansion franchise, the Dallas Mavericks, took part in the NBA Draft for the first time and were assigned the eleventh pick in each round. A player who had finished his four-year college eligibility was automatically eligible for selection. Before the draft, five college underclassmen announced that they would leave college early and would be eligible for selection. The draft consisted of 10 rounds comprising the selection of 214 players. This draft has the distinction of being the first NBA Draft to be televised.
Document 7: 2016–17 Indiana Pacers season: The 2016–17 Indiana Pacers season was Indiana's 50th season as a franchise and 41st season in the NBA. On May 5, 2016, despite making the playoffs, Pacers' president Larry Bird announced that Frank Vogel's contract would not be renewed, citing a need for "a new voice" to lead the players. On May 16, 2016, the Pacers promoted their assistant head coach Nate McMillan to become their new head coach.
Document 8: 1979 NBA draft: The 1979 NBA draft was the 33rd annual draft of the National Basketball Association (NBA). The draft was held on June 25, 1979, before the 1979–80 season. In this draft, 22 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip. The Los Angeles Lakers, who obtained the New Orleans Jazz' first-round pick in a trade, won the coin flip and were awarded the first overall pick, while the Chicago Bulls were awarded the second pick. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. Larry Bird would have been eligible to join this draft class because his "junior eligible" draft status from being taken by Boston in 1978 would expire the minute the 1979 draft began, but Bird and the Celtics agreed on a 5-year contract in time to avoid that. Before the draft, five college underclassmen were declared eligible for selection under the "hardship" rule. These players had applied and gave evidence of financial hardship to the league, which granted them the right to start earning their living by starting their professional careers earlier. Prior to the draft, the Jazz relocated from New Orleans to Salt Lake City and became the Utah Jazz. The draft consisted of 10 rounds comprising the selection of 202 players.
Document 9: 1992–93 Boston Celtics season: The 1992–93 NBA season was the 47th season for the Boston Celtics in the National Basketball Association. This marked the first season since the 1978–79 season that Hall of Fame player Larry Bird was not on the team. This was also the final season for longtime Celtics All-Star forward Kevin McHale, as he would retire the following offseason. During the offseason, the Celtics signed free agent All-Star forward Xavier McDaniel. However, the team got off to a bad start losing eight of their first ten games, but would post a nine-game winning streak in March to finish second in the Atlantic Division with a solid 48–34 record (only 3 games behind the previous year, when Bird was on the team). The Celtics held home court advantage in the first round of the playoffs against the 5th-seeded Charlotte Hornets, but during Game 1 of the series, All-Star forward Reggie Lewis collapsed on the court (Lewis would never again play in a Celtics uniform, and would die before the next season began). Boston held on to win Game 1, but (minus Lewis) lost the next three games, and thus the series.
Document 10: 1984 NBA Finals: The 1984 NBA Finals, also known as Showdown '84, was the championship round of the National Basketball Association (NBA)'s 1983–84 season, and the culmination of the season's playoffs. The Eastern Conference champion Boston Celtics defeated the Western Conference champion Los Angeles Lakers in a seven-game Finals, winning Game 7 111–102. Celtics forward Larry Bird averaged 27 points and 14 rebounds a game during the series, earning the NBA Finals Most Valuable Player (MVP). Bird was also named the league's regular season MVP for that year.
Document 11: 1988–89 Boston Celtics season: The 1988–89 Boston Celtics season was the 43rd season of the Boston Celtics in the National Basketball Association (NBA). This was the first season for Jim Rodgers as head coach. Rodgers had been a Celtics assistant coach prior to this season. This year's Celtics team was severely hindered by the loss of star forward Larry Bird to a heel injury which required surgery. Bird played only six early-season games before being lost to injury. Initially, Bird was expected back in March, but it was delayed and ultimately became a season-ending injury. The results were dramatic as the Celtics, who had averaged over 60 wins per season thus far in the 1980s, fell to just 42 wins in this season. Coming into the season, the Celtics had been the Eastern Conference's #1 seed five years in a row. This season they were the #8 seed, clinching a playoff spot in the season's final game. This season included some bright spots, particularly the emergence of guard Reggie Lewis, who had been only a minimal bench contributor in his rookie season of 1987-88, but averaged nearly 20 points per game as a starter in 1988-89.
