Beamer, who is intensely loyal to his staff and often cites the absence of significant turnover for allowing the Hokies to climb the ranks into college football's elite, decided change was in order. He is thought to have interviewed several candidates for the coordinator's job during the past few weeks.
Loeffler, 38, has coached for 15 seasons in the NFL and in college. He was the offensive coordinator at Temple in 2011 when the Owls finished 9-4 and ranked seventh in the nation with an average of 256.5 rushing yards. He moved to Auburn last season, and the inexperienced Tigers struggled mightily. They averaged just 305 yards, 115th out of 120 teams at the FBS level, and were 112th in scoring (18.67).
He has also coached six quarterbacks who went on to play in the NFL, including New England's Tom Brady and Florida's Tim Tebow, who left the Gators with five NCAA and 14 Southeastern Conference records.
Grimes, 44, spent five seasons at Auburn, including the national championship year in 2010, and worked with Loeffler last season.
Moorehead, 32, has been an assistant at Stanford for the past three years.
