The points differential in Super Bowl XLVIII was 35 points: the Seattle Seahawks defeated the Denver Broncos 43–8 on February 2, 2014.
Seattle dominated from the opening seconds. The Seahawks scored a safety on Denver's first offensive snap when the exchange between quarterback Peyton Manning and center Manny Ramirez went over Manning's head and out of the end zone. Seattle led 22–0 at halftime and never allowed Denver to mount a serious comeback.
The final score reflected a remarkable contrast between the teams. Denver had produced the highest-scoring regular season offense in NFL history at that time, while Seattle's defense—nicknamed the “Legion of Boom”—held the Broncos to one offensive touchdown. Seattle also scored through a safety, an interception return, and a fumble recovery.
The 35-point margin was tied for the third-largest in Super Bowl history at the time. Malcolm Smith, the Seahawks' linebacker, was named MVP after recording nine tackles, recovering a fumble, and returning an interception 69 yards for a touchdown.
