Current Record Belongs to Super Bowl LI With Over/Under Total of 57.5 Points
What is the biggest over/under line in the history of the Super Bowl?
The record for the highest ever over/under line belongs to Super Bowl LI (Atlanta Falcons vs New England Patriots) at 57.5 points.
The two teams both possess offensive juggernauts that are led by Tom Brady and Matt Ryan, respectively. Both teams demolished their competition to earn their way into Super Bowl LI, and both teams will look to put up significant numbers of points at Super Bowl LI.
Prior to Super Bowl LI, the record for the biggest ever over/under line for a Super Bowl game belonged to Super Bowl XLIV, which was contested between the New Orleans Saints and Indianapolis Colts. The over/under line for that game was 57 points.
Here are some of the other high totals in recent Super Bowl history:
Super Bowl XLII - New York Giants vs New England Patriots (55 points)
Super Bowl XXIX - San Francisco 49ers vs San Diego Chargers (53.5 points)
Super Bowl XIX - San Francisco 49ers vs Miami Dolphins (53.5 points)
Super Bowl XLVI - New York Giants vs New England Patriots (53 points)
Super Bowl XXXVI - New England Patriots vs St. Louis Rams (53 points)
Super Bowl XXXIII - Denver Broncos vs Atlanta Falcons (52.5 points)
What do all of these games have in common? They all feature at least one of the greatest quarterbacks in the history of the NFL, whether it be Tom Brady, Joe Montana or John Elway.
It's also interesting to note the explosion in offence that has taken place from the first couple of Super Bowls until now.
For a multi-year stretch, the over/under line in Super Bowl games sat in the low 30s. Over time, offences became more sophisticated and the over/under totals rose.
It seems to be just a matter of time until we see a Super Bowl contest with an over/under line of over 60 points.
