PHILADELPHIA — The proposed $765 million settlement of NFL concussion claims came under attack again Monday, this time from retirees who said they would get “nothing at all” for nagging health problems that limit their function. Seven former players filed a motion to intervene in the court case pending in Philadelphia, which aims to settle thousands of claims through a grid-like formula that reaches $5 million for younger retirees with Alzheimer's disease. The latest objections come from men who can perhaps still work, but say they still suffer from headaches, personality changes, trouble multi-tasking, and other side effects they link to concussions. — AP
