If the Bills' refs are inclined to be non-partisan with their calls, the Cowboys should manage to beat the Bills by 7 to 10 points or so. The Bills are mistake prone when it comes to playing the best NFL teams. I've seen games where I felt the Bills were given the benefit of close calls, imho. I don't think the weather will play a meaningful role in this one, with the forecast being favorable for both teams to do well. Something on the order of 52 degrees and no rain, with only 12 mph winds.
