Rivalry week is upon the Colorado State football team. For the second time this year, CSU will face an in-state rival when the Air Force Falcons roll into Hughes Stadium Saturday. After suffering a 41-10 blowout loss to No. 21 Boise State at home last weekend, CSU will look to get back on track and avoid losing its third game in a row. The Falcons (3-3) bring one of the nation’s top rushing attacks against a CSU defense that has struggled mightily against the run over the last three weeks. The Rams (2-4) face a critical juncture of their season, with their shot at bowl eligibility dwindling with each loss.
