For fun I created a 2010 player card. It is a pitcher I called Johnny Slider. So named because his slider is so good it unduces a gb(3b)A on every roll for his card. Results of a replay using 2010 American league with him pitching for the Seattle Mariners to provide advantage of a pitcher's park.
Results:
261 IP, 50 BB and 12 HRs. This is not against allstars. It was against regular 2010 AL lineups. This is the best pitching performance the game model is capable of reproducing. No matter how good a pitcher's control is or how good at keeping the ball in the park he will give up minimum numbers similar to these.
With this built-in bias towards offense is it any wonder historic pitching performances are never approached?
