Just so everyone is clear on what exactly the NBA’s ultimatum to its players is, David Stern detailed the nitty-gritty in a letter to the union leadership. Per the NY Times (which got a copy of the leaked missive): “A letter sent by David Stern, the commissioner of the N.B.A., to the players union Sunday contrasts the proposal on the table — highlighted by a 50-50 split of revenues — with a ‘reset’ proposal that would cut the players’ share to 47 percent, roll back current contracts, impose a hard salary cap and reduce contract lengths. The salary rollback, which was part of the N.B.A.’s first controversial proposal in 2010, had not been included in any league proposal for many months, and it was not publicly mentioned by Stern when he announced the ultimatum Saturday night. But the rollback was included in the letter Stern sent to Billy Hunter, the union’s executive director. A copy of the letter was obtained by The New York Times. The union has until 5 p.m. Wednesday to accept the N.B.A.’s last proposal or have it replaced by the reset proposal, Stern wrote. ‘Rather than simply proceeding, as we could have, to offer a less favorable proposal at this time, the N.B.A. is providing an additional period of time for the players association to consider our 50/50 proposal,’ Stern wrote. ‘We are hopeful that the prospect of a less favorable outcome for the players will prompt the players association to realize that the best deal that can be reached is the one the N.B.A. is prepared to make right now.’ Stern closes, ‘Billy, I sincerely hope that we can reach an agreement over the next few days.’”
