Heh bheid408, I like a lot about this theme, but I don't like not being able to determine your teams better.
(1) I have a very limited list of team seasons (about 3) that I enjoy to play, so -- although very unlikely -- if those seasons are gone, I won't want to play. Perhaps others would back out if that happens to them too? If I were able to secure my favorite team season upon signup, that would lure me in.
(2) One of my favorite team seasons has a huge flaw, so I would be hoping beyond hope that the 10 twisted players to fill that 7-player hole. I would prefer a setup that would allow more flexibility as to which teams I could twist from. Otherwise, I would be forced to take a more conservative team choice, which wouldn't be as fun. To me, making more flexible rules (like pick any 2 of the other teams in the league to make your twisted 10 players) maintains fairness and limits the chance for an owner to hate their own team (a real buzz-kill in my books).
Thanks for considering changes...
