Of all the teams on this list, Dallas had the best balance between offense and defense. But don't underestimate the Cowboys' offense. NFL rushing king Emmitt Smith ran for 1,713 yards and 18 touchdowns and Troy Aikman threw 23 touchdowns in '92. Dallas outgained its opponents by over 100 yards a game and seemingly scored whenever it really needed to. The Cowboys also averaged 38.7 points per game in the playoffs en route to a Super Bowl championship.
