Same here.
I used the pro stick for the post game 100% last year.
This year I use square. The post fades have not been dropping for me AT ALL. Use the left analog stick to choose which direction you want to shoot in and press square.
It's annoying, In 16 I could give a shoulder fake one way and pull a fade the other seamlessly, now I have to use the shoulder fake and then pull the left stick the direction I want to go and then press square.
You can rotate the shot stick, but forget it in the park.
