My league normally is 16 teams, points-based, head-to-head (two weekly matchups for all but the first three weeks of the regular season ... total of 39 games -- 5 x 3 division opponents, 2 x 12 non-division opponents).
I just sent out an email to the league throwing out a bunch of options (a lot will depend on if all 16 decide to play ... I'm leaving it open as possibly treating this season as separate from our history, maybe not even carrying over draft picks or keepers).
1. Head-to-head vs. all teams: Obviously a team going 15-0 (or 0-15) every week potentially will make a big difference in the final standings.
2. Partial-week head-to-head schedule: I don't think CBS even allows this, but we also are considering trying out other websites just for this season.
3. Purely points based season: Like Roto, but teams just would accumulate points from start to finish to determine the champion
4. Weekly points based: We could award an automatic playoff berth to the top scoring team each week, and then fill out the remaining playoff bracket (6 teams, 8 teams, whatever) with the top overall scoring teams that didn't win a week. This way, no team ever is out of it.
Open to any other ideas anyone might have.
