I have to follow up your answer with two questions.
1. How did you figure that Rushing out = Shooting and Communication = Finishing? By where they are located visually on the screen? or because you remembered (or had a record of) your GK's stats from before the change and found a correlation? Or was it a random guess that you proved through testing?
2. Are you saying that for you corner kicker you pick a player with high Shooting? (I would have guessed Crossing) And that for free kicks you pick a player with high Finishing? (I would have guessed Shooting).
