Kugler, a former UTEP player, worked with the offensive linemen and tight ends with the Detroit Lions from 2001 to 2005. He was the assistant head coach and offensive line coach at Boise State in 2006 before joining the Bills in 2007 as an assistant offensive line coach. He was promoted to offensive line coach in 2008, but the Bills fired their entire coaching staff last week.
Kugler also spent eight seasons at UTEP as an assistant coach and a graduate assistant.
