"We've embraced him. We all love him. He had a hand in recruiting everybody here. We have a rapport with him, so it's not like it's a new kind of thing. He has great energy, a great fire. He's young and passionate. That's all you can ask for."
Other assistants also have new assignments on the defensive staff. Andy McCollum moves from the line to inside linebackers. Joe Speed will coach outside linebackers instead of inside linebackers. Specials teams coordinator David Walkosky takes over the line.
"The first thing we want to be able to say is that everybody is lined up and knows where they're going, what to do, and then it comes down to you've got to win," Kelly said. "You can't play with 12 people, you can only play with 11, so somebody has got to win and that's what we try to emphasize."
Kelly said Georgia Tech's defense has enough talent.
"This game, it's not very complicated," he said. "There's no magical defense. If there was, everybody would be running the same thing. It comes down to players and first of all alignment, putting your eyes in the right place and being able to play fast on every snap.
"Alignment, pursuit angles, tackling, beating blocks, that's how you play defense. All correctable things."
Kelly insisted his focus is not on making this more than just an interim job.
"What I've tried to do is focus on Georgia Tech and its players," Kelly said. "I think if you work and do your job and do everything you can, work as hard as you can, I can live with the results.
"The main thing is coach is my boss, he's been very good to me and my family. He asked me to do a job. He made no promises. He just asked me to do a job."
