Frost reflected on his two seasons at UCF in the interview and noted that there are only a few places in the country where he'd like to be the head coach - a list that seemed to include Nebraska.

Frost served as a graduate assistant at Nebraska in 2002.
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 declined to comment all week on reports he had agreed to terms with Nebraska prior to UCF's AAC Championship matchup with Memphis. He played for the Huskers from 1995 to 1997 before an National Football League career with the New york Jets, Cleveland Browns, Green Bay Packers and Tampa Bay Buccaneers.
