Do you support Keeper or Dynasty leagues?
You can designate that your league is a “Keeper” league by selecting Commissioner→Manage League→General Organization on your menu. The players on your rosters will then be kept for the next season.
In addition we offer a League→Archive area where we keep final rosters, game results, standings, draft and transactions from year to year. In addition you can add additional info for things like league champion, most points, etc.
