The “defense wins championships” saying held true in the 2015 season when the Denver Broncos were carried to a Super Bowl 50 win by an outstanding defense. But there is a good chance that a team with a great offense and a below-average defense wins Super Bowl LI.
Of the eight teams still alive in postseason play, five ranked in the top seven in terms of offensive efficiency during the regular season, including each of the top four teams. Every remaining team except for the Houston Texans (31st) ranked in the top half of the league in that category.
