"John Mackey changed the game of football in more ways than one. The revolutionary combination of speed and strength that he brought to the tight end position enabled him to literally carry tacklers downfield for the kind of gains usually reserved for wide receivers. WIth teammates like Johnny Unitas and Raymond Berry, and under the guidance of legendary coach Don Shula, Mackey helped shape the powerhouse Baltimore Colts of the sixties and early seventies. He was a signuficant leader off the field as well- his work as the first president of the NFL Players Association paved the way for several landmark developments in sports labor. John Mackey was a true pioneer during the most eventful period in NFL history, and his life story is a fascinating read for any fan of the game."
