Thanks for the kudos,
I've had a few people ask me this, and while I greatly appreciate the offers, there's only one issue. Realistically, you can upload mine and create whatever you want. However, if I were to have you do the NFC teams, and I did the AFC teams, there really is no way to merge the two files without overwriting the other one.
I understand people are anxious to get their favorite team, but I am really trying to go for authenticity here, so it does take a little extra time. I think it'll be worth it in the end.
