Houston quickly plummeted from a potential Cinderella playoff to contender to a team that is unlikely to contend for the AAC title. The Cougars lost to a Navy team that is difficult to defend, but they allowed that loss to cost them another game as they slept walk through another defeat last week at SMU as a three-touchdown favorite. Accordingly, Houston is on sale Saturday against a Central Florida team that has made great strides in its first year under Scott Frost. But the Knights still lack the personnel and depth to hang with Houston if the Cougars are motivated.
