VT played a lights out defensive game against a largely inept offense. After the game our fans complained about the coaching and lack of adjustment but in retrospect it was very clear that the playbook was about one page long and the youth scattered around the field made adjustments damn near impossible. VT, to their credit, figured out quickly that OSU was not going to be a threat so they cut loose on D and simply crushed a weak OL and rattled a young QB.
The VT offense wasn't great but that wasn't as a result of great defense by OSU. The lack of offense was a problem that plagued VT the entire season and while I'm sure they'll produce a better product in 2015, the OSU D is going to be downright nasty this fall.
VT played like a 7-6 team against OSU. Made mistakes on special teams, mistakes on offense. No question it wasn't flawless. However, football is a game decided by the relative strength against weakness of opposing units. VT's overwhelming strength was defense and at the time of the game OSU's overwhelming weakness was offense. That glaring difference is what allowed VT to overcome a pedestrian offensive day.
In 2015 offense will certainly be a strength of OSU. At the very least it neutralizes the advantage of the VT D. The OSU D improved dramatically as the season wore on, the VT offense didn't. It isn't a stretch to say that the OSU D should be dominant in 2015. I don't know what the expectations for VT's offense might be, however nothing from the end of the 2014 season would indicate it will be an elite unit.
