The best way for you to follow this is to open our running free agency live blog — and don’t close the tab for like 10 days.Reunited?Could Kawhi be moved to Toronto or Dallas?We’ve already dipped our toes into trying to figure out what the LA Clippers will do this summer. The Aspiration investigation still hasn’t been resolved by the league (or if it has, it hasn’t been shared with the public yet). And the 35-year-old Kawhi Leonard (Happy birthday, Kawhi!) is eligible for a contract extension this summer. He has one year left on his deal, for $50.3 million.If Leonard can’t secure a new contract with the Clippers (are they waiting on the investigation?), then he could be on the move this summer. One of those places might be the Dallas Mavericks, according to The Athletic’s Christian Clark, Dan Woike and Sam Amick.Mavericks president Masai Ujiri has interest in reuniting with Leonard, multiple league sources with knowledge of Dallas’ thinking told The Athletic.
