First look at fantasy football for NFL Week 13: Don't forget about Raheem Mostert and Deebo Samuel

San Francisco 49ers rookie wide receiver Brandon Aiyuk entered Week 12 leading the team in PPR fantasy scoring with only 115.7 points, a figure topped by 82 other NFL players. In other words, 49ers options have not really aided fantasy football managers much since awesome tight end George Kittle and several of his valuable teammates left the lineup weeks ago. Perhaps the narrative changes after several influential options returned from injury for Sunday's critical 23-20 victory over the Los Angeles Rams.
