I'd be fine with that. But bad teams would still play good teams in their League.
I also had a though, and I'd like to see what others think: If we don't use the Yankees as a franchise, why not draft individual Yankees, who would be used in conjunction with your franchise's season. As an example, if you are using 2011, and you drafted A-Roid (!), you'd have to use his 2011 season. If your next season is 1999, then his 99 season, and so on. My only thing would be one Yankee per team...so maybe HoFers only (if there's 24 HoFers from 67-present).
