THREE THINGS TO WATCH

1. Air Force quarterback Tim Jefferson

Last Saturday at Colorado State, the sophomore, who has been hampered by an ankle injury, looked as healthy as he has since early in the season. Not coincidentally, he had his best game, completing 7-of-12 passes for 111 yards and two touchdowns and running the option smoothly. Jefferson will need to have another good performance today against a Black Knights defense that last season limited the Falcons to 174 yards and 10 first downs. Air Force, as always, primarily will rely on its rushing attack. But if Jefferson can make a few big plays in the passing game — as he did Saturday in the victory over the Rams — the offense will be far more dangerous.

2. Army wide receiver Alejandro Villanueva

The senior is 6-foot-10 and 283 pounds. Villanueva started 12 games at left tackle last season before first-year Army coach Rich Ellerson shifted him to receiver.
