South Alabama’s offense runs through a deep backfield. The trio of Keenan Phillips, PJ Martin and Trae’von Dunbar has combined for 1,146 rushing yards and 15 touchdowns, giving the Jaguars several ways to stay on schedule. Phillips led the way last time out with 157 rushing yards, three rushing scores and a 100-yard kickoff-return touchdown.

That ground game has fueled a scoring surge. South Alabama beat ULM 52-35 on October 3, then outlasted Arkansas State 56-49 five days later to stay unbeaten in Sun Belt play. Scoring 108 points across two games shows how quickly this offense can turn a close contest into a track meet.

Marshall’s defense is the clearest problem in this South Alabama vs Marshall matchup. The Thundering Herd are allowing 33.7 points and 447.3 yards per game, numbers that set up poorly against a backfield this productive. If the Jaguars establish the run early, Marshall will have a hard time getting off the field.

Marshall can move the ball, averaging 406.5 yards per game, but that production has translated to just 22 points per game. Stalled drives are a dangerous habit against an opponent that can score in bunches, because every empty possession widens the gap.

South Alabama also has enough through the air to punish loaded boxes. Jared Hollins completed 23 passes for 266 yards and two touchdowns at Kentucky on September 26, showing the Jaguars can push the ball when defenses commit to stopping the run.

At 59¢, Kalshi gives South Alabama a 59% implied chance to win outright. Between the Jaguars’ rushing depth, their recent scoring surge and Marshall’s defensive struggles, I make South Alabama a stronger favorite than that price suggests, which makes the road moneyline my pick.
