Player attributes

[fishfan2012_PSN]

Is there a tutorial out there that explains how the attributes for each card is applied. Particularly for pitchers. It’s confusing because I can dominate with some cards and find others impossible to use. For example, prospect Michael Kopech is my best pitcher. I can breeze through a 9 inning game on 90 pitches. You’d think I perform better with signature Hal Newhouser but I can’t seem to be able to control any of the pitches. All of his stats are jacked up and I have to think I’m misusing him somehow.
