According to NBA executives familiar with the league’s strategies, once the lockout is in place, the owners will push for a hard salary cap of $45 million, the elimination of guaranteed contracts and ask that the players swallow a 33 percent salary cut.

The concessions made in recent weeks, including the “flex cap” of $62 million and a guarantee of $2 billion in annual player payroll, will be off the table.

If this seems certain to guarantee the loss of the entire 2011-12 season, it is because there are owners who think it is necessary for the long-term viability of the league.
