Theoretically you bring out a decent point. However, there are many defenses that maintain their same plan from week to week, with some adjustments. They will usually stick to a plan, many times throughout a season, that they believe based on strength of roster to be able to work consistently. It's not that easy to make major changes to a defense. The same can be said for offenses on a lesser scale. All you have to do is look at the old Shannahan offense.................run it over and over and over again............and hope your strength allows it to work.Random thought and question. If you don't have an offensive identity and on a weekly basis, you simply try to attack the defenses based on what they do. Don't knowledgeable DCs know the weak spots in their own defenses and can easily look at what you did in previous games and counter what they expect you to attack? For example, if I'm a DC running a 4-3 with heavy Cover3 tendencies, based on the Texan's tendencies, don't I know the areas the Texans are likely to attack?
The reason for my random thought. I was reading the article below and this quote stands out, “It’s a game-plan offense so we’re gonna look at who we play and say, "Here’s what they do on defense, and here’s what we’re going to do to try to attack that."
Football is a complicated game, and few have the magic key to "open or close the door" consistently.
