For 2017, the NAL consisted of eight teams in a single-table format (no divisions or conferences). Four of the teams (Corpus Christi Rage, Dayton Wolfpack, High Country Grizzlies and Monterrey Steel) were playing their inaugural seasons, with three teams (Columbus Lions, Georgia Firebirds, Lehigh Valley Steelhawks) joining from the now-defunct American Indoor Football, and one team (Jacksonville Sharks) joining from the Arena Football League.

Each team was scheduled for 12 games (6 home and 6 away) with 2 bye weeks during the season. However, in order to satisfy their arena contract from their time in AFL, the Jacksonville Sharks were given eight home games, while the Corpus Christi Rage and Dayton Wolfpack were each only given five home games to balance the schedules. This was changed again when the Wolfpack were apparently unable to secure an arena lease, despite announcing they would play at the Nutter Center. Previously signed players reported on social media before the season that all players had been cut from the team, and as of February 20, all their home games were canceled.^[2]
