The NBA’s initial proposal for a new collective-bargaining deal called for a $45 million per team hard salary cap along with non-guaranteed player contracts and significant cuts in annual salary increases.

The details, spelled out in an April 26 memo issued by National Basketball Players Association Executive Director Billy Hunter, marks the league’s push for a major overhaul of the NBA’s economic model and emphasizes to players an aggressive bid to significantly slash costs and shorten contracts.

Hunter said in the memo that the NBA projects the $45 million hard cap number with a team’s total salary not to exceed the cap for any reason. The proposed hard cap as outlined by Hunter also would eliminate the current luxury tax provision, which penalizes teams with a dollar-for-dollar tax for the amount spent on player payroll exceeding the salary cap.

Hunter also alerts players to the league’s effort to alter the structure of current contracts while detailing the owners’ proposal that no player contract be guaranteed for more than 50 percent for the first $8 million in salary and 25 percent for any amount above $8 million.

The league also strikes directly at a team’s cap room to re-sign players at a maximum salary, known as the “Bird” exception, after hall of famer Larry Bird. Annual contract increases would be no greater than 3 percent for players meeting the Bird rule, down significantly from the current 10.5 percent increase, according to the memo. Owners also proposed that the Bird rule contract length be cut to four years from the current six-year length.
