Bad offenses that kept our defense out on the field much longer than teams with good offenses on that list. People tend to forget that the performance of the offense and defense are correlated. Teams with great high scoring offenses that control the clock give their defenses a much better chance to perform well. The defenses are fresher (defenses don't switch out its players much and they are expending more energy than offenses since they are reacting and chasing), defenses are usually in more favorable field positions and opposing offenses become more predictable if they have to play catch up with an opposing high scoring offense.
