Dennis "Denny" Green, former head coach for the Minnesota Vikings and Arizona Cardinals, died Friday morning, reportedly from cardiac arrest.
Green spent 17 years coaching in the NFL with 13 seasons as head coach.
Aside from his coaching accomplishments, Green is probably best-known for his "They are who we thought they were" line after his Cardinals blew a 20-0 halftime lead against the Chicago Bears in 2006.
Green's last coaching job was with the United Football League's Sacramento Mountain Lions. He was 67 years old.
