The image shows the fact that Matt Nagy has an offensive and defensive playbook. If the Bears had to change their defensive coordinator, it will likely not affect the defense. If a team's scheme changed based on personnel firings or hirings, that could give a variety to the user's experience and help to keep the mode fresh.
The game-planning element of football is nearly impossible to accomplish in a realistic way and it's hard to blame the Madden devs for choosing an approach that incorporates in-game attribute boosts on certain play types.
A well-planned game strategy does not always make a player better at particular areas of the game. Instead, it puts that player in situations that enable him to improve his performance through playing-calling. If my corner isn't able to protect their top receiver, it doesn't matter how much we concentrate on man coverage that week, we're not likely to take advantage of a number of Cover 1.
One way to make that happen more realistically might be forcing players to reduce the types of formations and play options they have to choose during a particular game. If you find yourself playing a team that excels at defending outside zone runs, then one week you might choose to add more runs that are outside the zone in your game plan.
