The Celtics struggled with a 5–6 start to the season, but then won 12 of their next 14 games, and held a 28–21 record at the All-Star break. They later on posted a 7-game winning streak in March, and won eight of their final nine games finishing second in the Atlantic Division with a 49–33 record, making their first playoff appearance since 1995.
