What’s the Biggest Blowout in Super Bowl History?

The Kansas City Chiefs and Philadelphia Eagles are set to face off in Super Bowl LIX at 6:30 p.m. ET at the Superdome in New Orleans.

The game is predicted to be very close, as the Chiefs currently sit as just one-point favorites over Philadelphia, per ESPN BET, which makes sense, considering these are supposed to be the best two teams in each conference.

However, that's not always the case, and to find the biggest blowout in the game's history, you'd have to go back to Super Bowl XXIV, which capped off the 1989 season between the San Francisco 49ers and Denver Broncos.

The 49ers wound up winning the game 55-10, which was and still is the largest margin of victory in Super Bowl history.

The star of the show was easily San Francisco quarterback Joe Montana, who finished the game completing 22-of-29 passes for 297 yards, five touchdowns, zero interceptions and a 147.6 passer rating.

49ers' running backs Roger Craig and Tom Rathman also combined rushing the ball 31 times for 107 yards and three touchdowns.

What makes that performance even more impressive is that during the 1989 regular season, the Broncos' defense was amazing ranking first in points per game allowed (14.1) and third in total yards per game allowed (275.4).

Broncos quarterback John Elway also had an exceptionally poor Super Bowl performance, completing 10-of-26 passes for 108 yards, zero touchdowns, two interceptions and a 19.4 passer rating.
