On the cusp of hundreds of millions of dollars in contract extensions, several of the NBA’s top young stars had a Friday call with National Basketball Players Association officials about the possibility of league-financed insurance policies to protect against career-threatening injuries in the bubble restart in Orlando, sources tell ESPN. Miami’s Bam Adebayo, Sacramento’s De’Aaron Fox, the Los Angeles Lakers’ Kyle Kuzma, Utah’s Donovan Mitchell and Boston’s Jayson Tatum — five players with significant star and earning power — talked with executive director Michele Roberts and senior counsel Ron Klempner about the NBPA facilitating talks with the league on possible insurance allowances for players, sources said.
