Unlike season-long lineup decisions, playoff-only leagues require projecting for the entire postseason prior to locking in your lineup ahead of Wild Card weekend. That includes weighing which players will go deepest into the playoffs, potentially jostling their overall ranking a full 10-15 spots higher because they capped the year off with a full game’s worth of snaps over their peers and, in some formats, double the points in the Super Bowl.
The Official FFPC Playoff Challenge — a format that’s invoked an equal amount of time, joy, and misery from myself over the last few seasons — homepage describes it best:
Each team will choose twelve (12) players from any of the 14 NFL playoff teams but ONLY ONE PLAYER PER TEAM.
