There are three openings for GMs:
Cleveland, with Lebron, DMC, Dirk, Holiday, Iguodala
Pelicans, with Anthony Davis and Wiggins
Pacers, with Chris Bosh, Wes Matthews, Mudiay, Winslow, Porzingis
Just watch out: the league is very clique-ish and unfairly managed. Thus, why 10% of the league left overnight.
