Don't know, maybe we have a different perception but when I 'm saying Good player I mean something special, something to remember, to put it in the hall of fame of your team.
For example your GK has avg rate less than 8, 9/16 clean sheets, 1 motm title in 16 games.
A GK with high q and semi-mutant skills.
I believe if you had a simple GK with some 110% with more balance skills and without sa, he could have the same stats.
