Top free agents, such as DeMarcus Cousins, Isaiah Thomas, JR Smith and Jamal Crawford, could play in the NBA this season. The rule changes which allow the teams to bring 17 instead 15 players will open the door to free agents to sign into open roster spots.
“Free-agent players such as DeMarcus Cousins and Isaiah Thomas — who were on NBA rosters this season — and those who weren’t — JR Smith and Jamal Crawford, for example — are eligible to sign into open roster spots.”
Cousins signed with the Lakers last summer, but suffered a torn ACL during pre-season. He was waived in February of this year. According to various reports, the Lakers might be interested in bringing Cousins back for the playoffs. Miami Heat is another team that could try to sign the 29-year-old center.
However, this will not apply to international players, who did not have FIBA clearances when the NBA season got suspended:
“Teams won’t be allowed to sign international players, such as Nikola Mirotic, who weren’t on NBA rosters this season. Players who were playing internationally and did not have FIBA clearance at the time the season was postponed would be ruled ineligible.”
