Frost, a native of Wood River, Neb., who quarterbacked NU to the 1997 national championship, had always been the clear No. 1 choice to replace former head coach Mike Riley even well before Riley was sacked.
Frost then took his talents to Eugene, Oregon where he became the wide receivers coach under head coach Chip Kelly from 2009-12.
It's understandable that Frost would feel at least some remorse, considering that he has done an incredible job of turning around UCF in the past two seasons.
Frost's 12-0 Knights defeated Memphis moments ago 62 to 55 in double overtime to win the American Athletic Conference Championship and UCF will likely play in the Peach Bowl. Frost, an alumni of Nebraska, has brought UCF to the precipice of a flawless season pending the result of Saturday's championship game. Specifically, 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.
He coached linebackers at Northern Iowa in 2007 and became co-defensive coordinator the next year.
Frost comes in with two seasons of head coaching experience at the University of Central Florida.
As for his playing career, Frost went 24-2 as a two-year starter for Nebraska at quarterback and joined the ranks of legendary Huskers when he guided NU to the 1997 national title.
College football insider Brett McMurphy was first to report the news on Saturday afternoon.
