Playoff Format
Eight teams qualify for the playoffs. The league is split into two conferences with six divisions and six teams make the playoffs from each conference. Three division winners from each conference will qualify for the postseason. Three wildcard teams will also make the playoffs from each conference. Winners of the Divisional Playoff rounds within each conference advance to their respective Conference Championship Games. Winners of the Conference Championship Games advance to ArenaBowl XXI New Orleans.
