As someone who feels more knowledgeable than my competition in most leagues, I prefer bigger leagues (14-16). So my ideal league is:
14 Team, PPR, TE Premium, non-idp
Live draft
Champion determined by total points (non H2H) through all 17 weeks of the regular season
AND - I just thought of this! - Genius!!!!
Bonus playoff element: all teams advance to the playoffs, the real NFL playoffs. Every owner competes in the playoffs and it's an all out total points battle throughout the NFL playoffs. If your players are on playoff teams your team has a chance to win the playoffs of your league. If I were commish, I would make this an additive to the league by charging an separate fee on top of the regular season league fee to anyone who elects to compete for the playoff winner. That way if some members don't want to participate, they won't by not paying the extra H2H fee. It will again be total points but all points reset to zero beginning with WC weekend.
