Thanks for quickly addressing my questions! Now here's an interesting thought. Can you add potential rating to the correlation matrix with the personality traits? I have always wondered if the game considered this in the potential rating, and you already have all of this data lying around
To my original point, I don't think anything in the correlation matrix explains why the highest desire for win players have a decreased rate. It would seem odd to me if that were true, but maybe they get unhappy too much in bad minor league teams and end up not developing or being traded around. Who knows.
