Louisville and second-ranked Miami have had their share of shootouts over the years. Both teams can still score, but the Friday matchup in Miami Gardens, Fla., also will feature the Atlantic Coast Conference’s top two defenses.Since 2019, the teams have combined to score 326 points in their past four meetings, including a 52-45 victory by Miami last season in Louisville. Entering Friday, the Cardinals (4-1, 1-1 ACC) are scoring 36 points a game, one more than the Hurricanes (5-0, 1-0).Those offenses will be tested. The Cardinals have the nation’s 12th-best defense and lead the conference, yielding just 262 yards per game. Right behind them in the ACC are the Hurricanes, whose 276.4 yards rank 16th nationally.Louisville’s offense, however, has not been a smooth-running machine all season.The Cardinals have turned the ball over at least once in each game, and quarterback Miller Moss has thrown pick-sixes in each of the past two games.On top of that, a botched pitch to running back Isaac Brown led to a scoop-and-score by Virginia in Louisville’s last game two weeks ago. The two defensive scores were key to the Cavaliers beating the Cardinals 30-27 in overtime even though Virginia gained only 237 total yards.Louisville also has a banged-up offensive backfield. As a result, a ground game considered a strength for the Cardinals entering the season has been limited to 107 yards on 61 carries through two conference games.The backs now face a Miami defense that has held opponents to 87.4 yards a game, the 14th fewest nationally, and 2.8 yards per carry, tied for 12th best.”We need to find ways to run the ball more effectively and be able to put some pressure on the defense that way, instead of having to throw the ball quite as much,” Cardinals coach Jeff Brohm said.
