And then UCF hit the afterburners for the current campaign - Frost's crew rolled to an 12-0 record, capped off with Saturday's wild shootout win over Memphis in the AAC Championship Game.
The University fired former head coach Mike Riley on November 25 after three seasons. "I hope I'm wrong, but there's little question in my mind now that Frost will be the next head coach of 'Huskers".
"I am thrilled that Scott is returning to his alma mater to lead the Husker football program", Nebraska athletic director Moos said in a statement.

Frost's success has happened with a dynamic offense he dubbed "UCF-Fast" and averaged a nation-best 48.3 points per game entering Saturday's game.
The New York Jets drafted Frost in the third round in 1998, and he spent six seasons as a safety with four National Football League teams.
He then went to OR to work as receivers coach under Kelly, and when Helfrich took over as head coach in 2013, he appointed Frost as his offensive coordinator and quarterbacks coach. Frost, a 42-year-old Wood River native, also faces the pressure of being the popular prodigal-son choice of fans who bought "Frost Warning" t-shirts and started "Bring Scott Frost Back to Nebraska" Facebook pages.
Frost will lead a Nebraska program in the midst of a two decade slide from national prominence that's included the firing of four coaches since 2003. "Specially, I would like to thank Coach Osborne who has played such an integral role in my life over the past two decades, both on and off the field".
