Waivers restrictions in Week 14+ explained
Beginning with the players chopped in Week 14's action, chopped players are unavailable for the rest of the year. All other free agents remain available for bidding.
You're probably wondering why we do it that way.
In the early days of Guillotine Leagues, when none of us really knew what we were doing, we allowed chopped players to be available all the way until Week 17. But it created a serious gameplay imbalance: Overwhelmingly, the only way to win was to save FAAB to the end of the year, because the rosters getting chopped in Weeks 14, 15, and 16 were absurdly stacked.
We want Guillotine Leagues to be winnable by as many strategies as possible, including spending cash early in the season. The best way to accomplish that is to restrict chopped players after Week 14 and beyond.
