In the NBA, there are 82 game players and there are 16 game players. Those players who are good for the regular season and players who are difference makers in the pressure cooker that is the playoffs.
Dwight Powell is an example of an 82-game player. He provides rim running and through sheer effort can maintain the integrity of a defense predicated on trust and timely rotations. Dwight Powell also showed he is not a 16-game player. He was largely unplayable in the playoffs and the Mavericks hoped they could survive his minutes whenever he was pressed into action.
