The formula for the 2015 Broncos on their Super Bowl run was simple: great defense with just enough offense.
The Broncos led the NFL in total defense in 2015, and despite having Brock Osweiler and a shell of Peyton Manning at quarterback, Denver went on to win the Super Bowl.
The Ravens are built in a similar way in 2017. The Ravens have great defense, and at times, just enough offense. The problem is, unlike the 2015 Broncos, the Ravens offense is too much of a burden for the defense to carry.
