This was a rematch of the 1978 NBA Finals, which the Bullets won 4–3. Seattle made a key offseason trade sending Marvin Webster to the New York Knicks for Lonnie Shelton. Other than that, both teams' rosters stayed virtually intact. Unlike the previous year, both teams finished 1-2 in the NBA, with the Bullets topping the league at 54 wins; the Sonics with 52 wins. In the playoffs, Seattle defeated the Los Angeles Lakers 4–1 and the Phoenix Suns 4–3, while Washington had a much tougher road, eliminating the Atlanta Hawks in an unexpectedly tough seven-game series and coming back from a 3-1 deficit to eliminate the San Antonio Spurs in seven. Both earned a first-round bye.
The Bullets controlled the game and led by 18 in the fourth, but Seattle mounted a furious comeback to tie it at 97. Larry Wright, who had 26 points off the bench, drove to the basket as time ran down and had his shot blocked by Dennis Johnson, but the referees called a foul on Johnson. Wright went to the line with one second left and hit two of three foul shots (NBA rules at the time awarded an extra free throw attempt when a team was in the penalty foul situation) to win the game.
Seattle dominated this game, which wasn't as close as the final margin indicated. Gus Williams scored 31 points, Jack Sikma had 21 and 17 rebounds, and Dennis Johnson had a fine all-around game with 17 points, 9 rebounds, and two blocked shots.
The Sonics won a close one in OT 114–112, staving off a late Bullets comeback behind 36 points by Gus Williams and 32 by Dennis Johnson. Williams and Johnson dominated the Bullets' guards all series, as they were plagued by poor shooting. Johnson also had four blocks in the game, the last on Kevin Grevey with 4 seconds left to ensure the Seattle victory.
Back home, Elvin Hayes had a hot first half, scoring 20, but injuries to starting guards Tom Henderson, Kevin Grevey and prolonged poor shooting by their replacements took their toll. Hayes had only nine points in the second half as Seattle closed out the series.
As of the 2014–15 NBA season this was the last Finals appearance for the Bullets/Wizards franchise. The SuperSonics would not return until 1996. That would be their last Finals appearance, since they relocated to Oklahoma City in 2008, as the Oklahoma City Thunder. The Thunder made it to the Finals in 2012.
