 The 1968 games were played under an experimental rule that eliminated extra point kicks and required a play from scrimmage to score one point (a rule later implemented by the World Football League in 1974 and the XFL in 2001).Games against non-league opponents were occasionally played after that time, usually with the NFL teams sending a rookie "split squad" to the game.In 1969, the Atlanta Falcons rookies defeated the Alabama Hawks of the Continental Football League 55–0,  and in 1972, the New York Jets rookies defeated the Long Island Chiefs of the Seaboard Football League 29–3.
