Expansion After a successful inaugural season, sixteen teams joined the league, its biggest expansion to date, bringing the a total of 26 teams.
Metro Manila is the region with the most expansion teams at seven, those being the
Makati Skyscrapers,
Mandaluyong El Tigre,
Manila Stars,
Marikina Shoemasters,
Pasay Voyagers,
Pasig Pirates, and
San Juan Knights. The
Pampanga Lanterns joined from
Central Luzon while the
Bacoor City Strikers,
Laguna Heroes, and
Rizal Golden Coolers, joined from
Calabarzon. As part of the league's national expansion, the five remaining expansion teams came from either
Visayas or
Mindanao. The
Cebu City Sharks from
Central Visayas are the only expansion team from Visayas. The four teams from Mindanao are the
Zamboanga Valientes representing the
Zamboanga Peninsula, the
Davao Occidental Tigers from the
Davao Region, the
GenSan Warriors from
Soccsksargen, and the
Basilan Steel from the
Autonomous Region in Muslim Mindanao (which later became
Bangsamoro). Mid-season, the MPBL side of the
Zamboanga Valientes was relaunched and became the
Zamboanga Family's Brand Sardines following undisclosed management issues.
Introduction of divisions Due to the much bigger size of the league, divisions were introduced to divide the teams into the North and South Divisions. Teams still play a single
round-robin tournament as part of the regular season, but the playoff format was changed to accommodate the new divisions. The top eight teams from each division would advance to an expanded playoff tournament. Similar to the
National Basketball Association (NBA), the champions from each division would face once another in what is dubbed the "national finals".

Coaching changes Roster regulation changes To ensure that the league remains balanced, a new rule was added so that teams were limited to only one Filipino-foreigner per roster, that player must also not be taller than 6'4" (193 cm). The player is classified as Filipino-foreigner if the player is a Filipino of foreign descent, regardless of being a Philippine passport holder. The new rule, however, caused some criticism from fans and players alike. == Regular season ==
