The lowest ranked rushing offense in the playoffs last year was the titans at 15. Super bowl champs were 3rd, the jags were 1st, the panthers and saints were 4th and 5th. Buffalo vikings chiefs rams and patriots were all top 10.
So it seems like running the ball is kind of important to winning, and to scoring points.
The defense part seems a bit unfounded too. Seattle was good because of defense and won a super bowl. Denver won a super bowl with gimpy armed peyton. The harbaughs played in the super bowl with top defenses.
