North Carolina's 4-8 record last season speaks volumes about that "development and culture." Their defense ranked 102nd in scoring, allowing 31.3 points per game. Virginia Tech finished with a better record and a dominant win over them, 34-17, by establishing the run and controlling the line. The Hokies' offensive line, which paved the way for over 180 rushing yards per game, was built through a mix of high school development and strategic portal adds. Sustainable football is about winning conference games, something the Tar Heels have consistently failed to do down the stretch. Their model hasn't produced an ACC Championship in decades, while Tech's foundation has.
