I agree that CPU vs CPU isn't affected at all. I didn't button mash at all with either of the pass rushers I used.
What really was the kicker for me was Armstrong winning on several of the rushes w PBK at 100. I think that not only would he never win against Smith irl but it also throws the ratings out the window.
I beat Smith 3 times by using a quick finesse move one button press all 3 times. Just way too unrealistic & also makes ratings almost useless imo
