Grading the keys

Grading the three keys B-Handle North Carolina's defensive front. The Tar Heels had three sacks -- one each by defensive tackle Tydreke Powell, end Donte Paige-Moss and end E.J. Wilson. Powell's forced fumble when Ryan Williams was carrying the ball with 2:02 left ended up being the game's biggest play. C+Buckle down on defense. North Carolina entered last night ranked 114th nationally in yards per game (289.4). But the Tar Heels looked impressive on offense at times, getting two touchdown drives of 84 yards and a field goal drive of 78. They also had runs of 23 and 44 yards and passes of 17 and 19. B+Don't dwell on past mistakes. The Hokies didn't appear to be affected by losing their last game, at Georgia Tech. But they still stumbled against a team they should have beaten. Now, they must try to find motivation in a season that is a bit less promising.
