Each owner will choose players, make up a starting lineup, make trades and sign replacement players. The season lasts 13-15 weeks and at the end of the season, usually coinciding with the NFL season, a playoff will determine the champion. If the teams choose to use a draft, they need to determine the order and select their players. If they choose to hold an auction then each team owner is given a set amount that they can use to sign 12-16 players. They can choose any combinations they desire.
Teams take turns bidding with the previous years winners going first.
The positions given to players at the beginning of the season remain the same all year even if the actual player changes positions. Owners may trade players any time before the 10th game. Once the commissioner has been notified then the trade is complete. The unit is one whole defensive lineup from a particular team. This lineup must the set up every week before the kickoff of the first NFL game each week.
