No. 1 Miami has rolled to a 7-0 start with a potent offense, yet Bill Belichick's North Carolina team carries a meaningful advantage into Saturday's game in Chapel Hill in one specific area.
The Tar Heels have been among the most disciplined teams in the country, drawing nearly half as many penalty yards as the Hurricanes through seven games.
North Carolina has been flagged only 28 times for 222 yards, an average of four penalties and 31.7 yards per game. Miami has drawn 48 penalties for 440 yards, averaging 6.9 flags and 62.9 yards each game. The gap between the teams amounts to 20 penalties and 218 yards.
North Carolina's Improvement
The Tar Heels lead the ACC in fewest penalties and fewest penalty yards per game and rank fourth nationally in both categories. The improvement stands as one of the biggest gains for Belichick in his second season. A year ago North Carolina averaged 6.6 penalties and 62.6 penalty yards per game, ranking 87th and 111th in the country.
Belichick has credited the change to greater player discipline. "It's the discipline of the players, and that's a lot better than it was last year on a lot of levels," he said. He also mentioned the value of building stronger habits throughout the program, arguing that the way players handle responsibilities off the field shows up in their execution on Saturdays.
The former New England coach divides penalties into three groups: those that occur before the snap, during the play and after the whistle. Pre-snap infractions demand concentration and preparation, while penalties during the action can be limited through better technique. Of North Carolina's 28 penalties, 15 have come during plays, 11 before the snap and only two after the whistle.
North Carolina has not drawn more than six penalties in any contest this season. The Tar Heels were flagged only three times against TCU, Notre Dame, Pittsburgh and Syracuse, and their season high of six came against Duke.
On the Miami side
In Miami's 52-3 win over Central Michigan on Sept. 26 the Hurricanes committed a season-high 13 penalties for 107 yards, including five false starts. Ten of the flags came on the offense, with holding, illegal formation and offensive pass interference among the others. Mario Cristobal made clear afterward that the mistakes were unacceptable even in a 49-point victory.
Miami had drawn only 13 penalties across its first three games combined before matching that total in a single afternoon against Central Michigan. The Hurricanes have been cleaner since then, but UNC still holds a sizable edge when the comparison is limited to conference games.
ACC Play
In ACC games Miami has been flagged 34 times for 328 yards over five games, an average of 6.8 penalties and 65.6 yards. North Carolina has drawn 17 penalties for 142 yards across four conference games, averaging 4.3 flags and 35.5 yards.
Belichick's team will need several things to go its way to upset the nation's top-ranked program. At least in the matter of avoiding penalties and protecting field position, the Tar Heels have already shown they can operate at a level Miami has not matched this season.
