Interstate Box Lacrosse Association

Colorado formed the first organized regional box lacrosse league with four teams after initial in-state competition in 2016. Seeing the success of Colorado's competition model, RBLL - Minnesota was formed using the same structure. The 2017 champions were the Parker Rangers, who took down the Hastings Walleye to capture the inaugural league title.

RBLL - New England and RBLL - New Jersey began play on the east coast under the IBLA structure. The midwest was organized into RBLL - Ohio and RBLL - Missouri. The second league title was awarded to the Cambridge Nor'easters after defeating the Denver Mile High Stars.

The IBLA expanded again, adding new competition on the west coast in the form of RBLL - Arizona and RBLL - California. Additional midwest talent was also brought into the fold with RBLL - Nebraska. The Maine Northmen came out on top in the playoffs, beating the Louisville Canards 17 - 14 in the final game.

Due to the spread of COVID-19, most teams faced shortened season schedules and the league championship tournament location was moved from Boston to Pittsburgh. By the end of the summer, 10 regions were able to crown division champions. Teams from these 10 regions were invited to compete for the IBLA Nationals league championship. For group play the teams were divided into the Steel and Maple groups. The San Diego Whalers, Grand Rapids Grizzlies, Mooncrest Munitionz, Aksarben Stampede, and Louisville Canards made up the Steel group. The Maple group consisted of the Maine Northmen, Philadelphia Phunk, Charlotte Reapers, Albany Hyenas, and Minneapolis Wheat Kings.

A league milestone occurred on September 17 with the first IBLA player taken in the National Lacrosse League Entry Draft. Mooncrest Munitionz Forward Larson Sundown was drafted by the New York Riptide in round 2 with the 36th overall pick. Sundown is transferring to RIT for the 2021 NCAA Lacrosse season, meaning New York will retain his rights through the 2021-2022 season. The 2020 IBLA season concluded with 25 playoff games from September 25 – 27. For the fourth year in a row, the championship matchup was played by two teams having never reached the title game. In the lowest scoring championship game to date, the Phildalphia Phunk outlasted the Minneapolis Wheat Kings 9 - 5 to capture their first title.

2021 will see the return of several teams that were on hiatus in 2020 due to local COVID-19 restrictions, as well as continued league expansion. The newly formed RBLL - Louisiana will represented by teams in Baton Rouge and New Orleans.
