Durant and Leonard are planning to talk with each of those teams once free agency opens Sunday at 6 p.m. ET, league sources said.
Leonard and Durant are each planning discussions and meetings with several teams, but only the Clippers and Knicks are in alignment with salary-cap space and common interest to sign both players. Brooklyn could conceivably house both, but a more likely scenario would be Durant and point guard Kyrie Irving signing as free agents with the Nets. Brooklyn is firmly Irving's focus in free agency, league sources said.
Leonard is expected to meet with the Los Angeles Lakers, Clippers, Knicks and Toronto Raptors upon the opening of free agency. Durant is planning conversations with the Clippers, Knicks, Nets and Golden State Warriors, league sources told ESPN.
