So to win games, the key for each team has been to minimize mistakes, avoid giving up big plays and cut down on penalties and turnovers.
So far, the difference is that the Cavaliers (5-2, 3-1 ACC) usually have operated within their margin of error, while the Tar Heels (2-4, 0-2) all too frequently have turned their games into a comedy of errors.
"That's youth, that's inexperience, that's losing momentum and then losing confidence," UNC coach John Bunting said of his team's penchant for mistakes.
Carolina has committed an ACC-high 18 turnovers while forcing a league-low 11. Virginia, by contrast, has committed 14 turnovers and forced 21.
The Tar Heels also lead the conference in another bad stat: penalties. The Cavaliers are the ACC's least-penalized team.
Otherwise, the two teams are similar. Neither has run, or stopped the run, effectively. Both have passed prolifically and been adequate on special teams. But little mistakes, and big ones, have made North Carolina a disappointment. Virginia, on the other hand, has been one of the league's surprising success stories with five straight victories.
"We haven't beaten ourselves this year, which we did sometimes last year," UVa linebacker Merrill Robertson said. "We let other teams beat themselves, or we help them beat themselves."
North Carolina is willing to take risks, which makes it a volatile but dangerous opponent. Sophomore quarterback Darian Durant is averaging more than 270 passing yards per game, easily the most in the ACC. And he doesn't dink his way downfield. He is averaging more than 14 yards per completion, a high number these days. His favorite target, senior receiver Sam Aiken, is averaging 17.3 yards per catch.
"This is certainly the most challenging passing game we've played against," Virginia coach Al Groh said.
The Cavalier secondary will have to be up for the challenge.
"I can't wait," cornerback Jamaine Winborne said. "We've proven that we can defend the deep ball. I'm glad they throw the ball deep. … They go for the big play, but that means we have a chance to make a big play too."
Durant has been personally responsible for 13 turnovers - eight interceptions and five fumbles. His Virginia counterpart, Matt Schaub, has been much more careful.
Many of the recent games in this series, the oldest rivalry in the South with 106 meetings, have been decided by mistakes. Last year, safety Dexter Reid's 67-yard interception return keyed North Carolina's 30-24 triumph. In 1996, a 95-yard interception return by Antwan Harris sparked UVa's 20-17 comeback victory.
Since 1982, the team committing fewer turnovers has gone 13-4-1. The Tar Heels have not won at Scott Stadium since 1981, a string of 10 straight road defeats. To end that streak today, they can't afford to goof up.
"I don't think we're going to get bigger, faster or stronger in one week - that's almost impossible," Bunting said. "But I think we can get smarter."
