As the Gems had recorded by far the worst record in the NBL, the Lakers had the first pick in the 1947 Professional Basketball League of America dispersal draft, which they used to select George Mikan, later to become one of the greatest centers of his time. With Mikan, new coach John Kundla and an infusion of former University of Minnesota players to replace those lost prior to the relocation, the Lakers won the NBL championship in their first season.
The next year, the Lakers switched to the 12-team Basketball Association of America (BAA) and proceeded to win the championship in that season. As the BAA is considered the direct lineal ancestor of today’s NBA, this 1949 BAA championship is recognized today as an official NBA championship for the Lakers, whereas their 1948 NBL championship is not. This makes the Lakers the most successful expansion team in NBA history, since the NBA does not recognize NBL records and considers the Lakers to be a 1948 expansion team.
