Roster regulations
Since the MPBL was a semi-professional league at the time, its initial set of roster regulations are made to help promote local talents:- Teams are required to sign three homegrown players into the roster. These players must be native to the locality in which the team is based in.
- A limit of five ex-professional players is placed on each team. Any player who has had experience in professional basketball is considered an ex-professional player.
