There is a myth that there is the perfect elite defense.. they are as rare as it gets. Most teams disguise their weakness very well and pass themselves off as a great defense.
The key to winning, isn't found in a single stat.. it is studying the opponent, identifying their weakness and being able to exploit them.
To be consistent game in and out.. you have to have the ability and the balance to be able to attack the opposition on any front.
You can win with a single faceted offense.. but if you truly want to be consistent and dominate.. you better be able to be able to do multiple things effectively.. because sooner or later a team you will run into will take away one or the other element of our offense.. and in game you will need to be able to adjust, force them out of their scheme and then hammer them with your strength.
You might think that only applies to offense, it doesn't.. the same is true on defense and most notably pass coverage. If you are cover two or zone defense.. teams will attack it and gouge you.. or if you are a man team they will employ presnap movement or stacked set and create natural space for the receiver release. You better be able to interchange effectively to adjust in game.. otherwise you are going to be attacked.
The equalizer is if you can dominate the line of scrimmage, but as you move on in the playoff, that is going to be less and less likely.
Again.. there is no single stat that will drive home a consistent dominate result.. pass happy, run happy, defense happy unless you possess a once in a decade type defense. I have seen two.. 85 Bears and 01 Ravens.. the rest.. great defenses, but they all could be attacked.
