What is 00 celtics?

As an AI language model, I infer that the "00 Celtics" refer to the Boston Celtics team during the 2000-2001 NBA season. Here are some pieces of information about the team:

• The 2000-2001 season was quite forgettable for the Celtics, as they finished with a 36-46 record, missing the playoffs for the first time in six years.
• The team's leading scorer that season was Paul Pierce, who averaged 25.3 points per game. However, Pierce missed a significant chunk of the season due to a knee injury.
• Other notable players on the 00 Celtics roster included Antoine Walker, who averaged 22.0 points and 8.7 rebounds per game, and Tony Delk, who had a career-best 16.0 points per game.
• The head coach of the team was Rick Pitino, who famously declared that "Larry Bird is not walking through that door" in a press conference, referring to the legendary Celtics player who was not going to come out of retirement to save the team. The quote became an infamous symbol of Pitino's struggles to rebuild the Celtics.
• In the following years, the Celtics would improve under the leadership of coach Doc Rivers and the acquisition of players like Kevin Garnett and Ray Allen. They won the NBA championship in 2008, breaking a 22-year title drought.
