Virginia Tech's defense not invincible

Posted by ESPN.com's Heather Dinich

BLACKSBURG, Va. -- The one area where Virginia Tech's defense is struggling is giving up the big plays, and it just resulted in Nebraska taking the 9-7 lead. Twice on the Huskers' last drive, the Hokies allowed Roy Helu Jr. 20-yard runs that put Nebraska in scoring position.

Nebraska's problem is its red zone offense. They can't punch it in. Zac Lee is doing a good job of scrambing just enough to keep the Hokies on their toes.
