Musical defensive coordinators between Falcons, South Carolina, Arkansas

Johnson said after 32 years in coaching, little surprises him. He was thrilled, though, to return to his native state.

"It was probably the last thing on my mind when I got up, but I was really happy when he called," Johnson said.

Spurrier said Johnson will receive a three-year contract, the same length as VanGorder's deal.

Spurrier said little was disrupted with VanGorder's departure since the new coach had not been entrenched in recruiting or planning.

Johnson has spent much of his three decades of coaching as a defensive coordinator, serving in that capacity at Mississippi State (2004-07), Alabama (1997-2000), Clemson (1994-96), Southern Miss (1988-89) and Appalachian State (1984).

Johnson said Petrino was disappointed.

"Coach Petrino's handled it with class. He's been in this profession long enough to understand these things," Johnson said. "He's been through a very tough, demanding change himself recently."

In a statement, Petrino said he spoke with Johnson "and he felt like this is the best decision for his family. I certainly understand that."

Johnson hadn't signed a contract with Arkansas. His wife and three young children were driving from Mississippi to Arkansas when Spurrier's job offer changed plans once again.

"You never know where you end up," Johnson said. "I've always had getting back to the state of South Carolina on the major college level in my sights."
