Been running the same league and format for about 6-7 years through NFL.com. 0.5PPR and no rule changes set from the default.

Like clockwork, every year at this time a few people will stop setting lineups or start selling to the 1st place team which takes away from a lot of the fun.

What changes have you made to your league to keep things interesting after the midway point to keep other managers from just giving up (outside of finding new people for the league)
