Nick's take:

Prediction: 49ers 28, Bills 10
Buffalo had little time to recover from its second-half meltdown against New England last week as it head into San Francisco, where the 49ers have won their last seven regular season games. San Fran has been a force on defense, the topper coming last week in their shutout victory against the Jets. An ailing backfield and a turnover-crazed Fitzpatrick will have a hard time against the league's third-ranked defense, and it will be a statement game for the Buffalo defense against a stout rushing tandem.
Dan's take:

Prediction: 49ers 21, Bills 10
Sean's take:

Prediction: 49ers 27, Bills 3
Sam's take:
The Buffalo offense has had no problem scoring, but when it comes to stopping other teams from doing so, they've been virtually non-existent. Expect Alex Smith to outshine a gunslinging Ryan Fitzpatrick here.
Prediction: 49ers 31, Bills 21
