Settlement Is Given a Mixed Reception When news circulated Thursday that the N.F.L. had agreed to pay $765 million to settle a concussion lawsuit, it was met with mostly positive reactions from some family members of players involved in the suit. Mary Ann Easterling, the widow of the former Atlanta Falcons safety Ray Easterling, called the settlement "tremendous" and "everything that I've wanted." Ray Easterling committed suicide in 2012 and an autopsy revealed he had a degenerative brain disease, chronic traumatic encephalopathy, which is known at C.T.E. and has become widely associated with athletes who have absorbed frequent hits to the head. "I am very thankful they have come to a settlement sooner rather than later," Mary Ann Easterling said by telephone from her home in Richmond, Va. There are so many players that need help, and this will provide some help to enable them to get care. This will make them somewhat whole. The terms of the settlement, which still needs to be approved by Judge Anita B. Brody of United States District Court, would include $675 million for players and families of players who sustained a cognitive injury, as well as $75 million for medical examinations and $10 million for the establishment of a research fund. The N.F.L. acknowledged no wrongdoing in its handling of head injuries. But players who have neurological issues, and their families, will now receive money to offset large medical bills. The family of Dave Duerson, the former Chicago Bears safety whose suicide in 2011 brought the issue of head injuries and the N.F.L."s responsibility to players who had them into even sharper relief, considered the settlement a "positive, not insignificant step toward improving the health and safety of football players going forward," their lawyer, Tom Demetrio, said. "The acknowledgment by the N.F.L. that these underlying cases that are pending in Philadelphia have some merit is a big deal," Demetrio said. Some were not as satisfied. Eleanor Perfetto, the widow of Ralph Wenzel, a former N.F.L. lineman who had dementia and died in 2012, said she could only comment on the dollar amounts she had seen in the initial news media reports, which she considered, "a big number, but I don't know that it's big enough." Reactions from other active and retired players were also mixed. The former Giants linebacker Aaron Curry, who is not part of the lawsuit, wrote on Twitter: "Settlement on concussions not gonna make up for early death, forgetting kids name and rest of stuff that come w/ brain trauma. Prayers. Oakland Raiders punter Chris Kluwe referred to retirees who are dealing with advanced neurological issues when he wrote: "Glad to see the older guys are getting taken care of with the concussion settlement. It'll never be enough, but it's a start. The Hall of Fame quarterback Fran Tarkenton, who was not involved with the lawsuit, considered the decision to be a "watershed moment" for the league and its players. "The N.F.L. is finally doing the right thing," Tarkenton said on "Moving the Chains" on SiriusXM radio. Our players were dying from Alzheimer's, and Lou Gehrig's disease, and dementia, and they said it had nothing to do with concussions. Now we know it does. Mary Ann Easterling said the person she thought of, after her husband, was his former teammate Wayne Radloff, who has suffered from the effects of brain trauma for the past seven years. "The N.F.L. rebuffed him repeatedly," she said. Now he and they are going to get help. Demetrio said: "We all envisioned six or seven years of catfighting. I think they understood the better part of valor is that the sooner we can quiet this whole issue down, the better it is for everybody. Mike Tierney and Tim Rohan contributed reporting.
