Billy Waddy (February 19, 1954 – January 21, 2022) was an American professional football player who played wide receiver for seven seasons for the Los Angeles Rams and the Minnesota Vikings. Waddy was a legitimate deep threat, who averaged 16.4 yards per catch over the course of his career. Relying on his speed and agility, Billy made big plays in one of the most significant games of his career—the Rams' shocking 21-19 upset of Dallas in the 1979 divisional playoffs, where he scored a game-winning 50-yard TD with less than two minutes to play.
