In most fantasy leagues, Week 13 is the end of the regular season. The owners with the most to gain—and lose—are those still fighting for a playoff berth, but that doesn't mean the intrigue is confined to the final few postseason spots. In many leagues, first-round byes are on the line, and those can be quite valuable. After all, it's easier to win two games than it is to win three, and a bye opens up that path to fantasy owners. Regular season championships, which are generally harder to win than playoff ones, are on the line in many leagues, as well. Those owners may have locked up playoff berths weeks ago, but don't tell them they have nothing on the line this week.
