Here a handful of statistical nuggets, with a tip of the cap, as always, to ESPN Stats & Info and sports information departments across the conference.
MARYLAND: Maryland leads the FBS in defensive expected points on passing plays (+69.5), and is one of two teams to allow just one passing touchdown. Defensive EPA is a measure of the expected points that a defense contributes to its net points in a game as a result of controlling field position, forcing turnovers and stopping its opponents.
FLORIDA STATE: Quarterback Jameis Winston has posted a Total QBR of 92.0, fourth highest among FBS quarterbacks. He has had at least two pass touchdowns in all four games and leads the ACC with 12. Winston has the fourth-best completion percentage (73.6 percent) and third-most yards per attempt (11.5) in the FBS. Last season, EJ Manuel had a Total QBR of 70.0, 26th among qualified quarterbacks.
VIRGINIA: The Cavaliers defense has posted back-to-back weeks of limiting opponents to less than 200 yards of offense for the first time since 1972. Virginia held VMI to 79 yards and Pitt to 199. When Virginia last accomplished this 41 years ago, it held Vanderbilt to 188 yards and VMI to 122. The Cavaliers area leading the nation in forcing three-and-outs, at 8.5 per game. Their third-down defense ranks No. 5 nationally, holding opponents to a .239 success rate.
NORTH CAROLINA: Quarterback Bryn Renner is one of six scholarship Tar Heels from Virginia, hailing from West Springfield. His father, Bill, was a Hokies punter from 1979-82 before playing for the Green Bay Packers. This will mark Renner's 30th career start. He leads the ACC and is 24th nationally in passing yards (279.3 ypg). His seven touchdown passes this year have given him 61 for his career, and he is seven away from Darian Durant's school record of 68.
VIRGINIA TECH: The Hokies picked off two passes in last week's upset win at Georgia Tech, giving them 11 for the season, the most in the nation. They had 13 all of last season. Since the start of the 200 season, however, they have tallied 251 interceptions, which are 20 more than any other FBS team during that time span. Not surprisingly, Virginia Tech's pass defense is tops in the ACC, surrendering just 138.2 yards per game through the air. Things may only get better for the Hokies if cornerback Antone Exum plays after being cleared to practice this week following his offseason knee injury.
BOSTON COLLEGE: The Eagles may just be the most disciplined team in the country under new head coach Steve Addazio. They have been penalized just eight times through four games, good for the nation's top mark (2.0 ppg). BC also leads the nation in fewest penalty yards per game (22.25).
NC STATE: The Wolfpack defense has been strong in the fourth quarter this season, giving up an average of 35.8 rushing yards, 38.5 passing yards and 74.3 yards of total offense over 60 total minutes of fourth-quarter action in 2013. NC State has forced five punts and five turnovers in 14 fourth-quarter possessions.
WAKE FOREST: Coach Jim Grobe is 31-10 for his career in games against fellow North Carolina schools, but he is just 6-6 against NC State, which has the best record against him among schools in-state. Grobe is three wins away from becoming the winningest coach in Demon Deacon history, as his 75 are two behind "Peahead" Walker.
CLEMSON: The Tigers are one of three FBS teams that have not thrown an interception yet. New Mexico and Oregon are the others. Of those three, Clemson has by far the most pass attempts (154). Oregon has 116, New Mexico has 54. Clemson has committed just two turnovers overall this season, tied for the fewest in FBS with Louisville and Oregon. Clemson also has 28 offensive touchdowns on plays of 25 yards or more since the start of last season, most in the ACC and tied for fourth-most in the FBS. The Tigers will be making their first trip to New York since Nov. 8, 1952, when they played Fordham to a 12-12 tie. Their only other game in the Empire State was an Oct. 2, 1937 loss to Army, 21-6.
SYRACUSE: The Orange are looking for their first win against an AP top-three team since 1984, when Dick MacPherson’s team knocked off Tom Osborne’s No. 1 Nebraska. Syracuse is 0-8 against AP top-three teams since then. Quarterback Terrel Hunt hasn’t exactly been tested yet, but he’s performed well in his limited action so far. Hunt has a 98.9 Total QBR on the year, but most of his participation came in two games: against Tulane and FCS school Wagner.
GEORGIA TECH: The Yellow Jackets will be playing their fourth conference game of the season, while Miami has yet to play its first ACC game. Georgia Tech is one of four schools in the FBS that has already played three or more conference games. The others: Pitt (2-1 ACC), Florida Atlantic (0-3 CUSA) and Air Force (0-4 MWC). To put it in perspective, there are 39 FBS teams that have yet to play a conference game this season (Note: This excludes schools transitioning to FBS).
MIAMI: Quarterback Stephen Morris has an 82.4 Total QBR in the first half and an ACC-low 10.3 Total QBR in the second half this season. The Hurricanes are 4-0 for the first time since 2004, when they started out 6-0 and climbed to No. 3 in the AP poll. They are also one of four schools to rank in the top 10 in the FBS in both scoring offense (ninth) and scoring defense (seventh).
