CHICAGO — Scott Frost talks to Tom Osborne almost every week. He welcomes his college coach into his office at Nebraska, or they go turkey hunting or fishing.

Hard at work at rebuilding his storied alma mater, Frost is keeping his friends as close as possible.

The 43-year-old Frost is home again after a successful run with Central Florida, returning to Lincoln in December after coaching the Knights to a 13-0 record last season. The long-term objective is moving Nebraska back into the upper echelon of college football, and the plan is a familiar one.

“Coach Osborne had the formula that Nebraska figured out,” Frost said. “Some of the things he did to make the program arguably the best in the country can still work today. Nebraska has just gone away from them. We’re going to adopt a lot of things again and do it in a modern way and do it in a way that recruits and kids are going to want to be a part of.”

Frost grew up about 90 minutes west of Nebraska’s campus and led the 1997 Cornhuskers to a share of the national championship in Osborne’s final year as coach. It was part of a wildly successful decade for the Cornhuskers, who went 108-16-1 in the 1990s.

But the program hasn’t enjoyed that level of success in quite some time. Mike Riley went 19-19 in three seasons before he was fired in November.

Enter Frost, who once again was unable to resist the siren song of his home state. Frost began his playing career at Stanford before coming home.

“Being a football coach is rewarding because of the time you get to spend with young men and the things you get to try to pour into them,” he said.
