The National Basketball League Coach of the Year Award was an annual National Basketball League (NBL) award given to the top head coach of the regular season in each of the twelve years the league existed. The Coach of the Year was selected by sports writers, broadcasters, coaches, and managers.[1][2] Interestingly, up until the end of the 1945–46 season, every coach that would win the NBL's Coach of the Year Award would also subsequently lead his team to the NBL championship as well. Following that season's end, Lon Darling of the Oshkosh All-Stars, Murray Mendenhall of the Anderson Duffey Packers, and Al Cervi of the Syracuse Nationals would be named the final winners of the NBL's Coach of the Year Award, though they wouldn't win the NBL championship in the subsequent years they earned that honor in question. The Oshkosh All-Stars had the most seasons where a coach of theirs earned that honor with it happening to them three different times, while the most honors for a head coach occurred three different times with Paul Sheeks of the Akron Firestone Non-Skids, Bobby McDermott of the Fort Wayne Zollner Pistons, and Lon Darling of the Oshkosh All-Stars each earning the award twice in their careers (Darling being the only one earning it in non-consecutive years). Sheeks, McDermott, and Darlins would end up earning the NBL's Coach of the Year Award for half of the years the NBL existed as a league.
