The 1977–78 NBA season was the team's 17th season in the NBA and their 5th season in the city of Washington, D.C.. It would prove to be their most successful season, as they would win their first and only NBA championship as of 2019. In the NBA Finals, they defeated the Seattle SuperSonics in seven games. The Bullets got off to a slow start in the regular season, losing 6 of their first 10 games. On January 13, the Bullets beat the defending Champion Portland Trail Blazers to improve to 24–15, capping an 18–5 run over 23 games. Injuries would begin to have an effect on the team as the Bullets struggled, as they would lose 13 of their next 18 games. Hovering a few games above.500 for the rest of the season, the Bullets managed to make the playoffs with a 44–38 record. This would be considered the worst team in NBA history to win a championship with its record of 44–38. The 1968–69 Boston Celtics, 1974–75 Golden State Warriors, 1976–77 Portland Trail Blazers, and 1994–95 Houston Rockets are the only other NBA championship teams to have won below 50 games in non-lockout seasons since 1958; all of them won more than 44 games.

NBA Finals
After being swept in their previous two trips to the NBA Finals, the Bullets lost Game 1 on the road against the Seattle SuperSonics, and a 19-point lead vanished in the process.
