If in fact I see potential ratings change through training and coaches hired, I will quit my bitching. However, I've yet to see documentation, statement, or actual sims I've done having potential ratings change. As we all know those potential ratings mean alot in trades, and like MLB 09 the show the ratings didn't change through training and such. If there is such a document, video, or post I've missed showing the changing of potential ratings through training as you say, I'd love to see it, because that would be an awesome addition to the game.
