The youngest unit on Virginia Tech's defense is the secondary.
It's where the Hokies can least afford injuries, and where they count on the leadership — and availability — of cornerbacks Kyle Fuller and Antone Exum to help their young teammates.
Yet, those two veterans made the glaring mistakes in the Hokies' 27-24 loss to Cincinnati last week.
Fuller let the Bearcats' Damon Julian get behind him for a 39-yard touchdown pass with 13 seconds to go, and Exum was called for four major penalties and missed a key tackle.
The Hokies (3-2, 1-0 Atlantic Coast Conference) will need to be better on the back end Saturday when they play at pass-happy North Carolina (3-2, 0-1) to begin their push toward an Atlantic Coast Conference title.
