You have to have a good QB and good passing game to win the Super Bowl. You also have to be good at defending the pass. There's plenty of ways to do it. The Saints defense wasn't exactly lights out when they won it. But, when you can build giant leads and score at will, it makes the defense's job easier.
What we need is a more consistent defense. We seem to have a defense that tends to play very well on the road...of all things...and then struggle at home. Then we will have some years where they are good at home, but poor on the road. Or a defense that starts out well, but struggles in the second half of the season or plays well in the first 3 quarters and wilts in the 4th quarter. Just no real consistency.
The defense needs to become great at the basics. It needs to tackle much better. It needs a better last line of defense (safeties) and it needs to be able to play both man and zone well. Once we get these basics down, then we can look to add the bells and whistles and add those key parts to make the defense run high octane. Otherwise we will still have the same inconsistencies and find ways to lose instead of finding ways to win.
