Cook lived most of his life in Chillicothe, Ohio, where he excelled in baseball, basketball and football while attending Chillicothe High School.
As a rookie in 1969 he led the American Football League's Cincinnati Bengals to wins over the eventual Super Bowl champion Kansas City Chiefs and the playoff-bound Oakland Raiders.
