Cameron Jones scored 19 points and Northern Arizona shot 54.5 percent from the floor against one of the nation's stingiest defenses in a 74-63 victory over Air Force on Wednesday night.
Shane Johannsen had 14 points and 10 rebounds, and Eric Platt added 12 points for the Lumberjacks (8-4), who improved to 4-0 at home.
Derek Brooks scored 15 points, Michael Lyons had 14 and Evan Washington 13 for Air Force (7-3), which was off to its second-best start in program history.
The Falcons came into the game ranked sixth nationally in field-goal percentage defense, allowing opponents to shoot just 36.1 percent from the floor.

Northern Arizona also held a 35-26 rebounding advantage.
