His name is Harry Hiestand and apparently (if you believe all of the internet chatter) he's leaving the University of Tennessee to join Coach Kelly's staff at the University of Notre Dame. Hiestand is a long-time offensive line coach who has five years of experience in the NFL with the Chicago Bears. He'll be replacing Ed Warriner who has apparently moved on to coach at the Ohio State University.
Welcome Coach Hiestand to the Notre Dame Family!
Here's a link to a video of Coach Hiestand with the media after a spring practice last April. You'll appreciate the cadence of his delivery -- he's a coach.
