You're right, aside from the W-L record being irrelevant the stats are realistic, but the rating drop is atrocious. Dickey and Colon are two of the most durable pitchers in baseball and suddenly after a year their overall drops from mid to low 80's to 67 each. The ratings mean everything in this game. It's what distinguishes between the good and the bad teams.
Go do your own simulation and at the end of the season go through every team and look for 35 and older players and try and convince me that that is a realistic drop-off.
