It was over.
Or so it seemed.
The Atlanta Falcons led the New England Patriots 21-3 at halftime during Super Bowl LI.
No team had ever erased a double-digit halftime deficit to win the Super Bowl.
But none of those teams had Tom Brady as their quarterback.
The Patriots would make history by climbing out of that 18-point halftime hole and stunning Atlanta 34-28 in overtime for their fifth Super Bowl title with Brady and coach Bill Belichick.
They also set the record for largest overall deficit overcome to win a Super Bowl, after Atlanta quarterback and league MVP Matt Ryan led his team on an 85-yard touchdown drive for a 25-point lead midway through the third quarter.
