The board hasn't posted a full number on this one yet. Before it does, the matchup is easy to describe: Army's run game against a Tulane defense that has given up 17, 24, 31 and 21, and Tulane's one proven big-play threat against an Army defense that just leaked chunk plays all night.
Army's offense isn't the problem. Samari Howard ran for 158 yards on 12 carries in Ruston, which is more than 13 yards a touch. Cale Hellums went 12-for-24 for 161 yards and found Brady Anderson 4 times for 79. Army moved the ball fine. The trouble was finishing drives, and an option team that leaves points on the field can't afford to also give up 70-yard plays.
Tulane's season has gone back and forth. The Green Wave scored 3 points at Duke and fell behind late at home against Southern Miss before rallying, and that win still needed TJ Smith to block a short field goal with 1:45 left. Those are the kinds of games you survive, not the kind you control. Tulane has played 2 Power 4 road games and lost both, by 14 at Duke and by 11 at Kansas State. This is its first true road test against a peer.
There's also a schedule difference. Tulane hasn't played since September 26, so it will have had 2 weeks to prepare for the option, and there isn't much in college football you'd rather have 2 weeks for. Army comes home on a normal week after the trip to Louisiana, sitting 1-1 in league play with WR B. Mott still listed out. The forecast calls for 65 degrees, clear skies and almost no wind. Expect a game decided by whichever defense gives up fewer explosive plays.
