At 8:20pm ET, my Sunday Night Total Of the Month is on San Francisco 49ers vs Buffalo Bills Under. If you're not experiencing it first-hand, you've probably heard about the snow and cold being felt in much of the country, including Buffalo. As a matter of fact, Bills have asked their fans to help shovel the stadium, for $20/hour. A little bit of cold doesn't affect the game too much. But extreme weather like this can and will. Purdy is questionable for the 49ers. He'd have to be better than Allen but still isn't going to solve SF's offensive issues single-handedly. Either way, the offense will struggle in the cold on Sunday. They're going to need the defense to elevate its level of play. They'll do their best to run McCaffery as much as possible to keep Buffalo on the sidelines. Play on the under.
