High Quality Content by WIKIPEDIA articles! The 1980 NBA Expansion Draft was the seventh expansion draft of the National Basketball Association (NBA). The draft was held on May 28, 1980, so that the newly founded Dallas Mavericks could acquire players for the upcoming 1980–81 season. Dallas had been awarded the expansion team on February 3, 1980. In an NBA expansion draft, new NBA teams are allowed to acquire players from the previously established teams in the league. Not all players on a given team are available during an expansion draft, since each team can protect a certain number of players from being selected. In this draft, each of the twenty-two other NBA teams had protected eight players from their roster and the Mavericks selected twenty-two unprotected players, one from each team.
