Who should bear the costs of retired NFL players’ medical bills?

Will this eventually end the NFL.... or radically change it?

Reggie Williams Story

After 24 knee operations, the National Football League’s former Man of the Year leans heavily on a crutch. When Reggie Williams pulls up his pants leg, what’s underneath looks like the trimmings from a butcher shop. His right leg is so ravaged that it’s three inches shorter than his left. Worse, it’s uninsured.
Once, Williams was the NFL’s high ideal. From 1976 to 1989 he was a spring-legged linebacker for the Cincinnati Bengals who set franchise records and played in two Super Bowls. Off the field, he was a civic-minded Dartmouth graduate who won humanitarian awards and served as a city councilman while he was still playing. He was so loyal to the game that he was a pallbearer at legendary team founder Paul Brown’s funeral. He would even be invited to apply for the job of NFL commissioner.
But now, Williams and his battered legs amount to a bill no one wants to pay. Since 2005 Williams, 58, has suffered a cascade of health problems he says stem from his 14-year football career, including multiple knee replacements and a bone infection, which he estimates have cost him hundreds of thousands of dollars out of pocket.
