National Arena League
|No. of teams||8 (as of November 30, 2016)|
|Headquarters||Ponte Vedra Beach, Florida|
Originally called the Arena Developmental League (ADL), it was founded in June 2016 by Columbus Lions owner Skip Seda and father Keke Seda in the wake of several small indoor leagues folding and teams jumping to other leagues. The league intends to play in March 2017 and, while not affiliated with any other leagues, plans on developing players to be looked at by scouts in the Arena Football League (AFL), Canadian Football League (CFL), and National Football League (NFL). In their introductory press conference, the league announced former AFL, af2, and CFL head coach John Gregory as its first commissioner and former AFL and af2 head coach Chris Siegfried as director of football operations. Charter teams began being announced in July 2016 with the Columbus Lions and Lehigh Valley Steelhawks joining from the defunct American Indoor Football. On July 21, the High Country Grizzlies announced their ADL membership after initially being announced as an AIF expansion team. On August 11, the Dayton Wolfpack were announced as the league's fourth team. On September 13, the ADL added the Georgia Firebirds from the AIF as the fifth team. On September 21, the league announced its sixth team to be from Highland Heights, Kentucky, owned by Northern Kentucky Professional Indoor Football LLC headed by W. Leland Bennett III. Bennett was one of the owners of the Northern Kentucky Nightmare, a travel team that played in the AIF the previous season, but no name for the ADL team has been announced and was removed from the league when the league later changed names. In October, the ADL added the Anderson Gladiators from Anderson, South Carolina, but were removed from the league in November due to arena lease issues. The Gladiators have since announced their intentions to join Supreme Indoor Football instead. On October 17, the Corpus Christi Rage held a press conference announcing it had joined the ADL (although the ADL did not confirm until October 28). On October 20, the ADL announced that the Fort Myers area-based Florida Tarpons were joining the league. However, the Tarpons would also withdraw from the league on November 10 to join the upstart Arena Pro Football.
On November 18, 2016, the league announced it had changed its name to National Arena League. As part of the change in name, the league management was also restructured so that it was no longer managed by Lions' owner Skip Seda, but was instead managed by all member teams equally. Later that day, the league added the former Arena Football League team, the Jacksonville Sharks. On November 30, the league added the Monterrey Steel from Monterrey, Nuevo León, Mexico, becoming the first American indoor/arena league to house a Mexican team as well as the first in fifteen years to house a team from outside the United States.
