NFL Hall of Famers Mike Ditka and Joe DeLamielleure continued their war of words with NFL Players Union boss Gene Upshaw on Monday, and introduced hobbled former offensive lineman Brian DeMarco, 35, as a prime example of the union's indifference to the medical needs of scores of ex-players. "This is unacceptable," Ditka thundered at a news conference organized by "Gridiron Greats" at his downtown restaurant. "We are past having committees. It's about right versus wrong. Do the right thing. Just do the right thing."
