The 2016 Super Bowl might be one of the most intriguing matchups in recent seasons because it involves the NFL’s No.1 defense and the league’s top scoring team. With the Denver Broncos set to face the Carolina Panthers on Sunday, the contest has a chance to be a shootout or a low-scoring affair.

The over/under for Super Bowl 50 has remained the same for much of the last two weeks, settling in at 45 points at Las Vegas sportsbooks and betting websites. No Super Bowl over/under has been lower than 45 points since 2004 when the Panthers last reached the big game.

Denver ranked first in total defense for the regular season, and their defense has been just as good in the playoffs. The Broncos limited the Pittsburgh Steelers to 16 points, while holding the New England Patriots to just 18 points. Pittsburgh and New England were tied for third in the NFL in regular-season scoring.

Led by MVP frontrunner Cam Newton, the Panthers scored 31.3 points per game, putting them behind only 15 teams in NFL history. Facing two top defenses in the Seattle Seahawks and Arizona Cardinals, Carolina has still managed to score 80 combined points in two postseason games. The Panthers have scored two defensive touchdowns in the playoffs, and they have a chance to add another one in the Super Bowl since they lead the NFL in takeaways.

Only six of Denver’s 18 games have totaled more than 45 points. In Carolina’s last 16 games, 13 have totaled more than 45 points.

Bovada offers the option to wager on several alternate point totals at different odds. Gamblers can bet on the total going under 55.5 points, though it comes with -450 betting odds. Taking over 30.5 total points for the game comes with -950 odds. The first-half total is 27.5 points, and gamblers can get +220 odds by betting the over. Denver’s team total is 19.5 points, while Carolina’s is 24.5 points.

The last two Super Bowls have exceeded the over/under, totaling 52 and 51 points. The Seahawks entered both games as the NFL’s No.1 defense.

Peyton Manning might be the best regular-season quarterback of all time, but his teams haven’t scored many points in his three Super Bowl appearances. When the Indianapolis Colts beat the Chicago Bears, Manning led the offense to a 29-point game. In Super Bowl losses in 2010 and 2014, Manning’s teams scored just 25 total points.

The over has hit in Denver’s last six Super Bowl appearances. Carolina’s lone Super Bowl appearance exceeded the total, as well.
