You still need a solid defense. Eagles probably don't win the Super Bowl without their defense. Really can't imagine the Eagles 7th ranked defense vs the Pats 30th ranked defense didn't have much of a difference in Nick Foles beating Tom Brady in a shootout. Also you want to talk about how the NFL's no. 1 total offense and 28th ranked total defense lost in the Super Bowl to a team ranked in the top 10 in both categories while starting their backup QB? Or about how the NFL's no. 1 scoring offense in the Rams last year couldn't make it past the wildcard round?
