I'd put it at like 49.. last year we beat Western Illinois by 39 points. And with what appears to be a greatly improved offense AND defense.. I think the spread will be a bit higher this time. The only thing that may lower it, is that BC may choose to rotate in some 2nd and 3rd stringers, maybe earlier than 4th quarter, as the depth-chart appears to be pretty close at some positions.
