The threat of an NBA lockout reaches beyond 30 teams.

National teams competing in important Olympic qualifying tournaments this summer could be affected, too.

The collective bargaining agreement between the NBA and the National Basketball Players Association expires July 1, and if a deal is not reached before then or shortly after, national teams are concerned they won't be able to obtain affordable insurance on players' NBA contracts.

NBA player contracts are insured in case of injury, guaranteeing a player will be paid if he is injured. In general, it's a 41-game deductible, giving teams some relief.

The insurance for NBA players in international events under normal circumstances — use last summer's world championships in Turkey with several NBA players as an example — works like this: The NBA's insurance company covers the player's contract, and the player knows he will be paid his NBA salary if he is injured. The national team pays an additional insurance premium to cover career-ending injuries in international play, but since career-ending injuries are rare, the cost is nominal.

The situation changes drastically in an NBA lockout. Players' contracts are suspended in a lockout thus there is technically no contract to insure during that period.
