Caption: Players Announce Strike -- John Mackey, left, of the Baltimore Colts and president of the National Football League Players Association, announced Thursday that NFL players have unanimously chosen to strike because their demand for a three-year, $26 million pension package has not been accepted by the NFL owners. Seated next to Mackey as he made the announcement in Chicago is Mackey's attorney, Allan Milier, of Detriot, Mich.
