No, this isn't Sim dynasty league. I think my title was a little misleading. Basically, you take the stats from the previous year (2003) and then kind of simulate/play a 162 game season. The real important categories are probably BA and WHIP. I don't completely understand how it works, but generally, if you are a .300 hitter, then in a game, there is a 30% chance that you will get a hit. Each hitter and pitcher are only allowed a certain number of games played, based on the previous season. I guess the software is trying to mimic the performance of each player in the prior season, adjusted for different line-ups, ballparks, etc.
