That may be the only way to explain Virginia Tech’s 23-21 football victory over North Carolina State at Carter-Finley Stadium on Saturday night. Coming into the Atlantic Coast Conference contest, the Hokies were 10-point underdogs and that made a lot of sense. Virginia Tech, meanwhile, had lost its first three games, fired its head coach and only gained its first victory last weekend over winless Wofford. Prior this season, this Virginia Tech program had one winning season in the past five. But in the first half Virginia Tech played like it was the favorite.
