Since the start of the 2012 season, Virginia Tech has a 24-20 overall record, and although the Hokies haven't endured a losing season in that team, that run is not exactly up to the expectations that Frank Beamer established. It's always hard to peg down exactly what it is responsible for a down-shift like this, but there is at least one obvious answer: quarterback.
The Hokies had two years of the ever-inconsistent Logan Thomas from 2012-13, followed by Michael Brewer's error-prone debut in 2015, and now a setback at the position thanks to injury. Brewer was in the middle of a quality outing against Ohio State before getting hurt, and who knows, maybe he was on the way to a surprise season that would revitalize the Virginia Tech season.
