It’s unclear what the Knicks would want back in a potential Smith trade. The degree of the Timberwolves’ interest in trading for him is also unknown. But one executive, speculating, said that getting a first-round pick back for Smith would be unlikely. Smith has competed with Elfird Payton and Frank Ntilikina for minutes at point guard. He has mostly come off the bench this season, a role he hadn’t filled much previously in his career.
