Two members of the owners' labor committee wrote to NFL retirees on Monday to outline elements of the offer the league made to the union during negotiations last month. Packers president Mark Murphy and Panthers owner Jerry Richardson, both former players, said in their letter that "the players' union wasn't listening" to the NFL's "significant offers that would have a measurable impact on the people who made football great." According to the letter, among the elements of the proposal were: a new pension supplement for retired players 55 and older; improvements to disability plans; a new rookie pay system that would shift more than $300 million annually to benefits for current and retired players.
