Also in the courtroom were former Eagles Dorsey Levens and Bill Bergey and the widows of several former NFL players. All are part of the suit, with more than 4,200 plaintiffs.
They knew that even if all or a portion of the case is allowed to proceed, it will take years for a suit to get through the courts. If any part of the consolidated suits is allowed to go forward by U.S. District Court Judge Anita B. Brody, the discovery process alone could take two or more years.
The plaintiffs also know there is a court of public opinion. The NFL can't exactly bring out healthy players claiming they have a safe game. In addition to the attorneys talking, post-hearing sound bites were provided by the former players and the widows.
"I knew I would have a bad back, bad neck and shoulders. I was willing to accept that," Turner said at the news conference held at a hotel on Chestnut Street. "But the fact that my brain has changed everything about me, that much I never knew."
Turner, 43, who retired in 1999 after five seasons with the Eagles and lives in Birmingham, Ala., was diagnosed with amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig's disease.
Researchers at Boston University have told Turner it is possible that instead of ALS, Turner has chronic traumatic encephalopathy, which mirrors ALS. His Alabama drawl, strong just a couple of years ago, has become slurred.
"I just really believe that this is from the many, many hits to the head," he said.
In September 2010, Turner described during a phone interview how he needed two hands to hold a cup. He could drive - he was doing the interview while he was driving - but needed two hands to turn the ignition key.
Now he is dependent on others.
"Putting on my pants, I had to bring a very good friend of mine," Turner said. "He helps me with everything from getting in the hotel room to brushing my teeth.
"Fortunately for me [the symptoms are] still in my upper body only. I haven't really had any considerable weakness in my lower body. My hands and arms I would say are less than 15 percent of what they used to be. In the last six months my speech has declined somewhat, as well as my breathing at certain times."
His close friend, Craig Sanderson, played football with Turner at Alabama and was his roommate. He lives less than 10 minutes away. The Sanderson family helps Turner with all sorts of tasks.
"He has no grasp at all. He can't pick up a straw," said Sanderson, who spoke of the courage Turner has shown in making his fight a public one.
Turner was one of the first former NFL players to make the decision to donate his brain to be studied after his death. There is more to his story, bouts of depression soon after he retired, an addiction to painkillers, a divorce.
"Between my wife and me and his girlfriend and [Turner's three] kids, it's kind of a group of people that help Kevin," Sanderson said. "Obviously there will come a day when he will need more full-time care."
Turner said he hasn't turned against the game. He'd play again, although maybe he would have played six seasons instead of eight, and maybe he wouldn't have been so quick to get back into games or onto the practice field.
There were a lot of leading questions thrown at him about whether the NFL did enough to educate him. He doesn't remember the subject coming up much.
Asked what he hoped to accomplish, Turner said, "A lot of it has already taken place. We've risen the awareness of the general public, which I think will help thousands and thousands of children playing sports today. I'm not beating up on football. It's soccer. It's a number of others."
He does believe decisions can't be left to players.
"I don't think as a 25-year-old football player . . . there'd be many who would tell the coach, 'Well, Coach, I don't think I'll go back in. There's been some research,' " Turner said. "That's a hard argument to make when you're on the field.''
