Former Iowa defensive coordinator Norm Parker has died at the age of 72.
A school spokesperson told the Associated Press that Parker died early Monday, and that more details would be forthcoming.
Parker was a mainstay of Kirk Ferentz's Hawkeyes program, holding the defensive coordinator from Ferentz's first season in Iowa City in 1999 until Parker's health-hastened retirement following the 2011 season. During his 13 seasons as the Hawkeyes' defensive play-caller, Iowa's well-drilled, risk-averse base 4-3 unit finished in the FBS top 10 in scoring defense four times.
Parker's 2009 defense ranked in the top-10 in total defense, yards per-play allowed and scoring defense, helping the Hawkeyes to an 11-2 record and Orange Bowl championship. The 2008 and 2009 Hawkeye secondaries both finished in the FBS top five in opponent's quarterback rating.
Parker had already been coaching for 31 years before arriving at Iowa, with stops at Wake Forest, Minnesota, Illinois, East Carolina, Michigan State and Vanderbilt.
Parker was a native of Hazel Park, Mich., and played his college football at Eastern Michigan.
