You need to apply each teams stadium sounds and players. For example, if you download the 20 Yankees, it will be full of Stadium sounds and player entrances/walkups. Applying these would put them on all Yankees rosters... with a hitch. If you want to play the 1972 Yankees, you would need to download our 20 Legends pack and find the players you need within. Again, adding the entrances/walkups to players. Stadium sounds would be done if you followed what we did before. As for recent players, I would suggest getting them from the 16, 17, 18, and 19 posts here on the forums. Hopefully that answers it for ya.
