I used vannwolfhawk's latest roster update(thank you and everyone involved for such a great base to work with) and added a ton of legends to the current teams. I scaled down every legend to a more realistic degree of authenticity and edited the contracts to most players so that there are no cap issues. I also filled all teams to 14 players.
I have placed all of the legends on teams based a bit on history and a bit on each team's needs. I don't know if anyone's interested in this kind of roster but I'm having a great time with them. It really fills the league out and creates a hell of a lot more competition each game. No matter how you use It most of the grunt work is done, small adjustments for user taste should be a lot less tedious.
If you're looking for the blended history experience give em a shot. There's a legend or two on just about every team...
