The Miami Heat must sign at least four players to meet NBA minimum league-wide average for a team, before the regular season begins to complete their roster for 2018-19.
Assuming Jordan Mickey and Luke Babbitt don’t return, and Miami guarantees Rodney McGruder’s contract, that leads to a choice of whether to resign Dwyane Wade, Udonis Haslem, and Wayne Ellington, or sign minimum contract talent in their place.
Miami’s situation is they have ten players under contract for next season, and they can fill the remaining 4 or 5 slots anyway they feel is best for the organization.
