Once upon a time the known championship week for the vast majority of leagues, Week 16 is not where champions are crowned anymore, but rather where teams fight for the honor of getting into the finals. With the addition of the 17th regular season game, Week 16 has turned into the semi-final in most fantasy leagues.
For the Falcons, with this week came a juicy matchup against the ever generous Detroit Lions defense (well, ever generous to everyone coming into this game except Kylar Murray, apparently). It was a defense which some fantasy owners likely targeted.
