The NNL split the season into two halves. St. Louis won the first half, Detroit won the second half. The teams met at the end of the season in a best-of-7 playoff series to determine the Champion.
The 1930 Kansas City Monarchs, managed by Bullet Rogan and Dink Mothell, missed the postseason after finishing the NNL1 regular season in 2nd place with a 40-23 record.
