SOUTH BEND, Ind. (WNDU) - Notre Dame football has added a new co-defensive coordinator and defensive backs coach to its staff as the team works through spring practices. Aaron Henry, who comes to Notre Dame after a stint at Illinois, is in his first season with the Irish. He has been working with Christian Gray and Dallas Golden at the nickel position this spring, aiming to add depth at that spot. Henry is applying his teaching background to help players learn in a more engaging way.
