Rookies and Retirees is the final theme available. With that being said, I have been site mailed by a couple of our most tenured members, who are willing to swap teams.
If you just can't make R & R work, site mail me with a division or 2 that you would like to try, and I will see if there is anything I can do.
(I really like the R & R roster I have entered, though. Hopefully you can become similarly inspired!)
