Owners and players initially found reason for optimism during Tuesday's meetings. Commissioner David Stern and Peter Holt, the head of the owners' executive committee, felt that the players' proposal to take 52 or 53 percent of basketball-related income, compared to 57 under the previous agreement, was basically fair, sources said. Owners were seriously considering coming off of their demand for a salary freeze and would allow players' future earnings to be tied into the league's revenue growth, a critical point for players. The owners also were willing to allow the players to maintain their current salaries, without rollbacks, sources said.
