ESPN reported that Dennis Green, legendary coach of the Minnesota Vikings and Arizona Cardinals over 13 NFL seasons died Friday morning at the age of 67 after a cardiac arrest.
While he coached the Vikings, they made eight playoff appearances in 10 seasons, reaching the NFC Championship Game in 1998 and and 2000. He led the Vikings to a 15-1 regular season in 1998.
When Green coached the Cardinals, he may have been best known for his "They are who they thought they were" rant after they blew a 20-0 halftime lead to the Chicago Bears in 2005, ESPN reported.
During his career he was also a head coach at Northwestern and Stanford at the collegiate level and was the first Black head coach in the Big Ten conference.
Many have taken to Twitter to express their grief.
Rest in peace Denny. I lost my mother in April, I feel like I just lost father.
