Guy Holliday coached at BYU for three seasons. He joined the BYU coaching staff as receivers coach in February 2013. He came to BYU with 20 years of coaching experience, including 15 seasons coaching receivers. 

He was part of an offensive staff that guided BYU to a top-25 passing offense in 2015 after the Cougars ranked No. 14 in the nation in scoring offense in 2014, putting up 37.1 points per game—the most points by a BYU team since the 2001 season. In 2013 BYU ranked No. 14 in total offense.

Holliday has helped 24 players advance to the NFL, including 23 at wide receiver. He has also coached tight ends, quarterbacks and running backs and served six seasons as an offensive coordinator during his career. One of those receivers he helped coach is Cody Hoffman, BYU's all-time leading receiver. 

Holliday spent the previous five seasons from 2008-12 at UTEP as the wide receivers coach and recruiting coordinator. The Miner passing attack was one of the most prolific in school history during that period, averaging just over 3,000 yards each year.  As a Miner, Holliday produced some of the program’s top receivers in Jeff Moturi and Kris Adams. Morturi (06-09) finished his career with 170 receptions, 2,527 yards and 26 touchdowns while Adams (07-10) finished with 144 catches, 2,657 yards and 30 touchdowns. Both rank in the top-7 among UTEP’s career leaders for each category.

Holliday was the wide receivers coach at Cornell for the 2007 season. Under his direction, Zac Canty earned honorable mention All-Ivy League honors after registering 49 catches for 447 yards. Canty was Cornell's first All-Conference wideout in four seasons. Holliday worked with a young wide receiver corps whose top 11 pass catchers were underclassmen. From 2003-06 Holliday worked in the Southeastern Conference at Mississippi State as the wide receivers coach. With the Bulldogs, Holliday coached All-SEC receiver Justin Jenkins, who recorded 62 catches for 882 yards and nine touchdowns as a senior in 2003. Jenkins went on to play in the NFL with the Philadelphia Eagles and Buffalo Bills.

Holliday spent three years from 2000-2002 at Western Michigan University, coaching wide receivers two years and tight ends one season. The Broncos had three all-conference receivers and one all-conference tight end under his tutelage. Holliday was also in charge of the special teams area at Western Michigan, with his kickoff and punt return units ranked among the conference's best. Holliday helped the Broncos to a 9-3 mark and the MAC Western Division title in 2000.  

He served six seasons as an offensive coordinator, three at Alabama State (1995, 1998-99) and three at Tuskegee University (1992-94), while also coaching quarterbacks, receivers and running backs. Achievements at Alabama State included the top-rated passing offense in the Southwestern Athletic Conference after guiding an offensive attack his first season that ranked No. 8 in Division 1-AA in scoring at 32.7 points per game. At Tuskegee, the Golden Tigers rated second in Division II in scoring in 1992, averaging 38 points per game, and were in the national top 10 in passing offense all three years. 

Holliday’s coaching career started with a one-year stint at Clark-Atlanta University as the running backs coach where he coached two 1,000-yard rushers, including the late Chuck Evans who went on to play eight seasons in the NFL.

Holliday earned a bachelor's degree from Cheyney University of Pennsylvania in 1987 and has three children — Justin, who is currently a wide receiver at UTEP, and daughters Schyuler and Christi.

Holiday on coming to BYU: “I’m excited about this opportunity. BYU has an outstanding history of football excellence and also academic excellence. I look forward to embracing the spiritual elements of BYU and helping young men be successful.”
