There is no additional charge to play in a Dynasty SimLeague -- however, you must purchase all seasons up front. You are required to have enough incomplete teams in your account to cover the length of the league. One incomplete team is good for one season of a Dynasty SimLeague. So if you wanted to play in a six season Keeper League, for example, you would be required to have six incomplete teams in your account prior to joining the league. Once you join the league all sales are final. We will not be able to remove you from a Dynasty SimLeague before it is finished (all seasons played).
