You can edit any player and their abilities, and just not the way they look. Sign a minor leaguer that looks the way you want to the maximum term (seven years) at the lowest amount, even though they may get upset later in their career. Then, change their name, abilities, position, etc. This also works for changing other major league players. For example, you can change Joe Young on the Giants to Barry Bonds by editing everything except his appearance. By doing this, you can sign an entire team. Note: You can only re-negotiate contracts at one year to seven year contracts at about $1 million each or less, then make them "gods". Note: You can only re-negotiate contracts at one year; when you are finding a player to make your own, look for one year contracts.
