The 13 Team Fantasy Football League Schedule inserts what we call a dummy team, which takes the place of what would be a bye. This format can be used for all leagues with an odd number of teams. We have went into more detail about Running a Fantasy Football League with an Odd Number of Teams. Each week the dummy team's score will be computed by using the average score of all teams. The 13 team league will have every team in the league playing every other team in the league 1 time. The top 6 or 8(your choice) teams would advance to the playoffs which begin week 14. If you only advance 6 teams, seeds 1 and 2 would receive byes in the first round.
