Buffalo Bills DVOA, Stats, & NFL Rankings

Buffalo Bills running back Ray Davis has remained in a reserve role since Week 6 but holds value as a bench stash entering Week 13. The rookie only averaged five touches per game over the last four contests. If anything happens to starter James Cook, Davis would be the most valuable waiver-wire addition. Fantasy managers, especially those rostering Cook, can get ahead by adding Davis to benches. He should not be started against the San Francisco 49ers.

Buffalo Bills wide receiver Amari Cooper (wrist) does not carry an injury designation into the weekend after fully participating in practice all week. His route participation may increase against San Francisco. He's been a part-time player since his arrival in Buffalo before Week 7 but had the bye week to better acclimate to the Bills system. Fellow outside wide receiver Keon Coleman (wrist) will be inactive. However, the San Francisco pass defense is above average against fantasy football wide receivers. Sunday Night Football also has weather concerns (snow, wind). Cooper is considered a risky start in Week 13.

Buffalo Bills wide receiver Khalil Shakir has five straight games with at least six receptions as the slot receiver for quarterback Josh Allen. He has 18 more catches than the next Buffalo Bill. As Allen's go-to receiver, Shakir ranks as a WR3 against San Francisco. However, the 49ers are one of the best defenses against slot receivers this season. Plus, Shakir hasn't scored a touchdown since Week 3. Shakir should still see plenty of targets but there are some reasons to be concerned about him matching his typical stat line.

Buffalo Bills running back James Cook projects to see plenty of usage on Sunday night against the San Francisco 49ers. The 49ers are fairly weak against fantasy football running backs this season, allowing the 10th-most points per game. Most recently, Josh Jacobs ran for 106 yards and three touchdowns against them. Cook can beat defenses on the ground or through the passing game. With the potential for hazardous weather in Buffalo, Cook may hear his name called more often. He's ranked as a high-end RB2 in Week 13.

Buffalo Bills quarterback Josh Allen enters Week 13 as a model of consistency for fantasy football. He's scored at least 20 fantasy points in six straight games and is the QB5 in fantasy points per game this season. In Week 13, the Buffalo Bills host the reeling San Francisco 49ers. The defense is generally strong against quarterbacks but there are injuries to a few key players, including All-Pro pass rusher Nick Bosa. There's a chance of snow in the forecast, which could hamper offensive production. Nevertheless, Allen has been too good to fade and should be in all starting lineups this weekend.
