It's difficult to accurately capture the Madden 22 coins aspect of football in an accurate fashion. Therefore, it's hard to take the blame Madden developers for choosing an approach that incorporates in-game attribute boosters based on certain types of play.
A good strategy won't automatically make a player better at specific aspects of the game; Instead, it places the player in situations that help make the job easier, through play-calling. If my top corner isn't able protect their top receiver regardless of how much we focus on man coverage in the coming week, we're never capable of being able to take on a large amount of Cover 1.
One way to capture that more realistically is to require players to reduce the plays and formations they're forced to pick from during a particular game. If you're faced with an opponent that excels at defending outside zone runs in one game, you may consider including more plays that involve outside zone running to your game plan.
This is a way to enhance the role of the coaching staff. Being able to hire a better-rated coordinator may let you include more plays in the game plan every week. A poorly-rated assistant could limit your play-calling choices.
I am a fan of the addition of Mut 22 coins adjustments, and this idea could carry to my system.
