The year 2018 kicked off with a first for Roster Wars as all 24 Main League owners returned to start the season. The newly implemented practice squad was a hot topic during the January Owner's Meeting as rules were tweaked to allow free promotion during the contract assignment period and a cost of 5WB was assigned to a Poaching Team giving a 1-year deal. Proposals to expand the practice squad, remove the trading deadline and to allow suspended players to be placed on injured reserve were defeated.
The Minor League saw seven new owners and two dispersal drafts. The Cyclone City Falcons, Coachella Tremors, CryptoTown Deliverers and Detroit Disco Lemonade joined the Promising Prospects Conference replacing the Faber College Mongols, MobTown Ravens, Valhalla Viktors and Andromeda Afterglow. Meanwhile, the ToonTown Warlocks, Windy City Blitz and Las Vegas Juggalos joined the Rising Rookies Conference to replace the Kalamazoo Nukes, Carolina Werewolves and North Carolina Cobras. A sudden departure of the Manhattan Beach Patriots after the dispersal drafts were concluded led to the Rising Rookies Conference also gaining the Florida Chaetomorpha as Main League owner Stylianos stepped up to take on the vacant franchise.
