Warren Moon
Harold Warren Moon (born November 18, 1956) is an American former professional football player who was a quarterback for 23 seasons. He spent the majority of his career with the Houston Oilers of the National Football League (NFL) and the Edmonton Eskimos of the Canadian Football League (CFL). In the NFL, Moon also played for the Minnesota Vikings, Seattle Seahawks, and Kansas City Chiefs. Moon is considered one of the greatest undrafted players in NFL history.Moon began his professional career with the Eskimos in 1978 after not generating interest from NFL teams. His success during his six CFL seasons, five of which ended in Grey Cup victories, resulted in him being signed by the Oilers for 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. Moon led the NFL in passing yards twice, while also receiving nine Pro Bowl selections. He spent 10 seasons with the Oilers, who he led to seven playoff appearances, and made an eighth postseason run with the Vikings before retiring in 2000.
At the time of his retirement, Moon held several all-time professional gridiron football passing records. Although relatively unsuccessful in the NFL postseason, his five consecutive Grey Cups from 1978 to 1982 remain a CFL record and he was twice named Grey Cup MVP. Moon was inducted to the Pro Football Hall of Fame in 2006, becoming the first black quarterback and the first undrafted quarterback to receive the honor. He is also the only player inducted to both the Pro Football Hall of Fame and the Canadian Football Hall of Fame.
