During the 2011 NFL lockout, it seemed a day wouldn't go by without a retired player ripping the league and its Players Association for both for what was perceived as inadequate medical, insurance and disability treatment. And while all sides have taken steps to address the issues involved more forcefully, there are currently more than 4,800 former players involved in concussion-related lawsuits, according to NFLConcussionLitigation.com.
And to be clear, there are still plenty of individual players who feel slighted on principle if not specific grounds. In the video, former Green Bay Packers tight end Gary Knafelc suggested the league is just waiting for those who complain to "die off." Knafelc played for the Packers from 1954-62 and went on to serve as the public address announcer at Lambeau Field from 1964 to 2004.
