Frost came to UCF from Oregon, where he was an assistant coach from 2009-15, ascending to offensive coordinator in 2013. In 2009, the Ducks ranked 33rd in total offense and eighth in scoring. One year later, they climbed to first in the FBS in both categories, and never dropped below sixth with Frost on staff.
Oregon won at least 10 games each year from 2009-14, and had a 79-11 record during Frost's tenure before he accepted the role at UCF. The Ducks appeared in the national title game in 2010 and 2014 along with the Rose Bowl, Fiesta Bowl and Alamo Bowl.
Frost was the offensive coordinator as Marcus Mariota won the Heisman Trophy following a 2014 campaign where he threw for 4,454 yards and 42 touchdowns with just four interceptions. Mariota completed 66.8 percent of his passes with 105 passing touchdowns and 14 picks as a Duck, as well as rushing for 2,237 yards and 29 touchdowns from 2012-14.
Frost originally kicked off his career on the sidelines as a graduate assistant at Nebraska in 2002, then held the same role with Kansas State in 2006. His first full-time position came as the linebackers coach for Northern Iowa in 2007 and then as co-defensive coordinator in 2008. Both of those seasons the Panthers appeared in the FCS Playoffs.
