The PBL had massive turnover of franchises and began the 2009–10 season reduced from 13 to 9 teams, playing as a single division. Four teams of the old Atlantic Division returned, except the problematic Montréal franchise. But the entire Midwest Division disappeared. Battle Creek, with the league's best record, quit the PBL over the PBL's decision to hold a one-game league championship in Rochester, denying Battle Creek up to two home dates, and over disagreement over compensation for this decision. In the Eastern Division, Rochester and Buffalo returned, but the Wilmington franchise left, reportedly over loss of nearby competitors. However, the Maryland GreenHawks (formerly the Nighthawks) came out of dormancy, and the PBL picked up the Lawton-Fort Sill Cavalry from the Continental Basketball Association; and the Capitanes de Arecibo, from the Baloncesto Superior Nacional league of Puerto Rico.
