Dennis Green had a fascinating career in football before he died Friday at the age of 67.
Green played briefly in the CFL. He coached under Bill Walsh at Stanford and with the San Francisco 49ers. Green was only the second African-American college head coach in NCAA history at Northwestern and the first in Big Ten history. He won four division titles and made the playoffs eight times in his 10 seasons with the Minnesota Vikings and widely was considered one of the most successful African-American head coaches in league history before Tony Dungy won a Super Bowl.
