Below are the aggregate total sweeps recorded in our database. The data includes only NBA data (including the BAA from 1947-1949) since according to the ABA-NBA merger agreement, the NBA does not officially recognize the ABA history.
The data is split between the First Round, Semifinals, Conference Finals and League Finals, but the league’s playoffs were not always in this format. From 1947 to 1974, there were only three rounds to the playoffs. For these seasons, the “first round” of the playoffs is considered the Semifinals in the data below. From 1949 to 1969, the NBA was divided only into Divisions, it was not until 1970 that the Divisions were upgraded to Conferences. For those seasons, the Division Finals is synonymous with Conference Finals.
In 1975, the NBA added the “First Round” which is labeled as such below.
*Note: In 1950, the first season after the BAA merged into the NBA, there were three divisions. The three Division Finals games are included in the Conference Finals data and the two winners with the worst records played a game to determine who makes the Finals. That extra game is also included in the Conference Finals data below.
*Note: The High Seed is the team with Home Court advantage.
