Is team quality calculation just.. stupid?

[Cloverfield]

Formation: 3w-1-2-3w-1
Defense: 1GK and 3Dw fixed players


Only position that was not decided the DMC.
So with all other players in defense fixed, I tried to decide between below 3 players:

I wanted to check how defense overall quality of team would be calculated, using each one of them.
I wanted to believe that there is some kind of “weight” in the calculation so the player with higher defense % would boost the defense overall % much more.
So:
4 fixed players with Escamez (120% Q – 159% Def Q)

4 fixed players with Zemanek (120% Q – 148% Def Q)

4 fixed players with Kovcas (124% Q – 115% Def Q)



So it seems that I had the higher defense % using the higher player in Q on the overall but the way way worst in defense Q.
This is just stupid...

I am starting to feel that training individual or boosting the "defense"/"attack" characteristics of a player is even more cosmetic than green peppers on a pizza.
