As a Hall of Fame cornerback for Vince Lombardi's Packers, Herb Adderley earned accolades covering the best wide receivers in the National Football League. Forty years later, he can't cover his bills. America's most popular sport finds itself facing a daily blitz of accusations by Adderley and other retired players clamoring for better benefits from a union portrayed as insensitive to their needs. NFL Players Association head Gene Upshaw, a Hall of Fame guard who broke in with the 1967 Oakland Raiders, has been demonized as a bought-off executive who has turned his tailored suit on retirees grappling with shabby pensions and an array of medical issues linked to the violent nature of pro football.
