Pretty sure that Poo-Diddy DOES NOT edit ratings when doing rosters. The only exception this year are the player potential ratings for prospects in which he used a consistent method to categorize them (read his thread for details). Other than that, they already have full minors and I'm 99% sure the major leaguers are not touched minus transactions, lineups and rotations. Console edited also; enjoyed his NCAA rosters very much.
Now for the real question...PS2 or XBox fellas? Right now, there's no word on conversions being made for XBox. Definitely some requests, so maybe if you want them bad enough it could happen. Such rosters do exist though...
No problem.
