If I owned PT, I would make it so that no cards ever changed. No starting pitcher would see a change in Stuff when forced to be a Relief Pitcher. No player could learn how to play a different position. Make the ratings we see be the actual ratings, with no hidden gimmicks and tricks to alter them and make them better.
