Bracketless bracket
Developed by Bill James, in a bracketless bracket office pool you pick one team per seed (so one #1, one #2, etc.) and you get points for each game your teams win. Points per win go up as seed goes down (10 points per seed): wins by your #1 seed pick are worth 100 points, but wins by your #16 seed pick are worth 250 points.
Sounds awesome.
