Another idea that I just thought of...
(Only if we use real fighters, otherwise disregard this message)
In addition to the free agent pool idea, perhaps we could have a trading block thread where deals can be worked out because if we do draft you know you'll have someone you won't want at the end of the day, and it could add to the fun of the league if there was that kind of extra interaction. Maybe not, though. Just figured I'd type it anyways.
