The NPBL formed around the former NBL/NBA teams, with larger-market teams added. The charter teams were the East Division Red Skins, Anderson Packers, Louisville Alumnites and Grand Rapids Hornets, and the West Division Denver Refiners/Evansville Agogans, Saint Paul Lights, Kansas City Hi-Spots and Waterloo Hawks. Sheboygan posted the NPBL's best record (29–16) in 1950–51. Sheboygan and Waterloo finished first in their respective divisions, but the league did not conduct a playoff and dissolved at the end of the regular season. Both teams claimed the championship, based on division play.
