Warren Moon

Harold Warren Moon is an American former football quarterback who played professionally for 23 seasons. He spent the majority of his career with the Houston Oilers of the National Football League and the Edmonton Eskimos of the Canadian Football League. Moon also played for the NFL's Minnesota Vikings, Seattle Seahawks, and Kansas City Chiefs. He is considered one of the greatest undrafted players in NFL history. Moon played college football for the Washington Huskies, winning Pac-8 Co-Player of the Year in 1977 and being named MVP of the Rose Bowl at the end of the season. Due to not generating interest from NFL teams, he began his professional career with the Eskimos in 1978. Moon's success during his six CFL seasons, five of which ended in Grey Cup victories, resulted in him being signed by the Oilers in 1984. During his 17 NFL seasons, Moon was named Offensive Player of the Year in 1990 after leading the league in passing yards and passing touchdowns.
