Manning appeared in eight games as a true freshman for the Hokies, registering four tackles and a interception during the 2012 season. After entering preseason camp atop Virginia Tech's depth chart, Manning fell behind freshman Kendall Fuller and Brandon Facyson. Facing the prospect of reduced playing time Manning decided to transfer.
Manning's tenure at Virginia Tech had not been without controversy. Last May he was charged with possession of marijuana and falsely identifying himself to a police officer. The marijuana charge was dropped but, Manning was convicted of the other offense and received a 60-day suspended jail sentence, one year probation, and $250 fine. He also picked up three minor traffic charges in Montgomery County (VA) during his time at Tech.
As a high school senior, Rivals.com ranked Manning a four star prospect. He chose Virignia Tech over scholarship offers from Alabama, WVU, Florida, and Florida State among many others.
