Recommended players - how the engine works

[Killroy]

I have yet to come across a good defender. I have one DR as backup for my 4 man defense. I did not get any defenders as recommended players. I got str/aml and str/amr though and both my AML and AMR are 6-7 star players with shadow striker and have good backups with the same SA. My striker is 7 star btw with free kick SA.

The recommended players are at least based on your quality. Low quality teams will get 4 star recommended players of 19 years for something like 19-29 tokens. I will only get 69-79 token offers for 20 year old near 7 star players.

Can anybody explain why defenders only get the free kick SA when they are offered? I mean living wall and headers are far more important. A DC/DMC with playmaker is also something you would like. But free kick???
