What's at stake?
Army opens its defense of the Commander in Chief’s trophy. A victory over Air Force sets up a winner-take-all outing against Navy — which beat Air Force 34-7 last month — for the CIC trophy on Dec. 14 in Landover, Maryland. The unbeaten Black Knights look to extend their nation’s best winning streak to 12 games, dating to last season. Air Force can end a six-game losing streak.
Key matchup
This rivalry game is generally won in the trenches. Army’s offensive line has paved the way for the nation’s No. 1-ranked running game. The Black Knights have started the same five players up front through the first seven games. Air Force’s defense has struggled against the run, allowing 205 or more yards in four of its losses.
Players to watch
Air Force: LB Osaro Aihie. Aihie will need to be active and effected inside if it wants to slow Army's ground game.
Army: RB Tyrell Robinson, who made his season debut in a win over East Carolina. The senior, who has game-breaking speed, is one of only 12 players in academy history to surpass 3,000 all-purpose yards. After one carry last game, Robinson could play a bigger role.
