Utah coach Kyle Whittingham announced the hiring on Wednesday. Holliday became available after former BYU coach Bronco Mendenhall accepted the head coaching position at Virginia.
Also, Lewis Powell moves from tight ends coach to defensive line coach, and Fred Whittingham Jr. takes over the tight ends after serving as Utah's director of player personnel the last four years.
Holliday replaces former receivers coach Taylor Stubblefield. Powell takes over the position vacated by the retirement of defensive coordinator John Pease.
