Renamed for a former team that played in Brooklyn after gaining new ownership, the Atlantics were a .500 franchise for 4 years. The advent of the divisional format helped the team greatly - they won a league record 103 games. The Atlantics defeated the Pittsburgh Alleghenys in the league's first championship series.
