In the first round, Indiana defeated the Atlantic Division champion 2004-05 Boston Celtics season in seven games, winning Game 7 in Boston by the decisive margin of 97-70, just the third time the Celtics had dropped a Game 7 at home. The Pacers then advanced to the second-round against the 2004-05 Detroit Pistons season, in a rematch of the previous years Eastern Conference Finals. The series featured games back at The Palace of Auburn Hills, the scene of the brawl that many assumed at the time had effectively ended the Pacers season. After losing Game 1, the Pacers won the next two games to take a 2-1 lead. However, the Pacers could not repeat their victories against the Pistons and lost the next 3 games, losing the series 4-2. The final game (Game 6) was on May 19, 2005; Reggie Miller, in his final NBA game, scored 27 points and received a huge standing ovation from the crowd. Despite Millers effort, the Pacers lost, sending Miller into retirement without an NBA Finals in his 18-year career, all with the Pacers. Miller had his No. 31 jersey retired by the Pacers on March 30, 2006 when the Pacers played the Phoenix Suns.
Output (English): How many times did the Pacers not make the playoff from 1991 to 2005?
