The 49ers offense faces not only a disruptive Cleveland defense in Week 13 but also some nasty weather. The extended forecast is calling for a mix of rain and snow with wind gusts up to 30 mph and temperatures that “feel like” 27 degrees. Niners QB Brock Purdy is mired in turnover troubles while the Browns will start rookie QB Shedeur Sanders. I’m grabbing the Under early in the week before books take a chunk out of this number due to the forecast.
