Navy defense vs.Troy offense: The Midshipmen will be challenged again by a fairly proficient passing attack, and a more than respectable running game. Led by junior quarterback Corey Robinson, the Trojans rank 15th in the country passing (315 yards per game) and 15th overall in yardage (488.7). But Robinson has nearly as many interceptions (eight) as touchdown passes (nine). Troy racked up 721 yards in a 55-48 shootout loss at Tennessee last week and has 11 passes of 40 or more yards and six of 50 of more yards this season, eighth-best in the country. Navy has overcome early 10-point deficits in two of its last five wins, as well as a late eight-point deficit at Air Force, and the defense has usually come up with big stops or turnovers when it mattered. Senior linebacker Keegan Wetzel leads the defense with 12 tackles for loss, including six sacks, but Troy's offense line has surrendered only seven sacks, none in the Trojans' two games against Southeastern Conference opponents (they also lost to Mississippi State, 30-24, on Sept. 15).
