My stacking percentages forecast has Air Force scoring 41 or 45 points, both with roughly equal probablity to Colorado State's 17 points.
The non predicitive public gauge shows Force winning 31-14.
I think this explains much of the early line movement. It remains to be seen if there are Colo St backers, maybe at 14, perhaps some at 13.5, that can support the price and halt the rise.
