Minnesota defensive coordinator Corey Hetherman, who helped the Gophers to an 8-5 finish, including a 5-4 mark in the Big Ten, has resigned his post to accept the same position at Miami, sources told ESPN's Pete Thamel on Saturday,

The Hurricanes ranked 68th nationally in scoring defense, allowing 25.3 points per game — a number that ballooned to 30.8 points per game in conference play. In Guidry’s first season as defensive coordinator, Miami allowed an average of 22.8 points per game but only gave up more than 40 points in a game once compared to three times this season.
