Setting the season length in a Points league
I am the Commissioner in a Points league. No head-to-head. Whoever has the most total points at the end is champion. I noticed on the head-to-head option you can set the length of your season. So if you wanted the last week of competition to be week 16, you can do that.
As far as I can tell, in a Points league you cannot set the length of your season. It's 17 weeks, period. However, our league, for example, does not want to play week 17 because many NFL teams are sitting their starters on the final week of the regular season. It would be nice for Points leagues to be able to have the fantasy season end in 14, 15, or 16 weeks according to whatever the league's needs are.
