Tychaun Chapman caught the touchdown and then converted the two-point try that finished Marshall's double-overtime rally past JMU at Bridgeforth Stadium on Nov. 30, 2024, a 35-33 loss the Dukes led 17-0 at halftime. That night sent Marshall to the Sun Belt Championship Game for the first time, against Louisiana. It is the only stadium in this series that has never gone James Madison's way. Marshall also won 26-12 in Harrisonburg in 2022, and both JMU wins in the Sun Belt era, 20-9 in 2023 and 35-23 in 2025, came at Joan C. Edwards Stadium. Marshall returns Saturday at 3:45 p.m. ET on ESPNU.
Everything else about the Dukes right now argues the history is just history. James Madison won 46-20 at Old Dominion on Saturday, and the defense was the reason it stopped being a game, with nine sacks, tying the program's FBS single-game record, 12 tackles for loss and minus-14 net rushing yards allowed. Camden Coleman threw four touchdown passes. George Pettaway ran 16 times for 110 yards, and Seth Cromwell scored a touchdown in the second half. JMU opened Sun Belt play 4-0 overall and 1-0 in the league.
That matters more than a normal September rout because of what the roster looks like. Billy Napier took over after Bob Chesney left for UCLA following the 2025 playoff run, and Sun Belt coaches still picked JMU to win the East with 11 of 14 first-place votes. Old Dominion was the first conference opponent to test whether that vote was about the program or the players still in it, and the answer was emphatic in the only way a road win by 26 can be. Marshall is the second test, and it is the one JMU's own building has never passed.
The identity question this specific opponent asks
The 2025 champions ranked sixth nationally in rushing offense at 241.5 yards per game and fifth in rushing defense at 85.1 yards allowed. That formula is what Napier inherited, and the defensive line's afternoon in Norfolk was the season's best sign it survived the roster turnover, though minus-14 rushing yards is partly a sack-inflated number rather than a clean reading of stopping designed runs.
Marshall is a strange opponent to measure it against. Marshall's defense gave up 458 yards against FCS Gardner-Webb, including four touchdown passes. If the Dukes get to the quarterback the way they did in Norfolk, the venue history should not survive the afternoon.
Quarterback and kicking notes worth tracking this week
JC Evans has not started since the opener. The July competition between Evans and Coleman, who threw for 2,031 yards and 13 touchdowns as Richmond's 2024 starter, never got a fair hearing. Napier said back on Sept. 14 that the injury was lower-body rather than a wrist and that Evans was "day-to-day, week-to-week"; by Old Dominion week, reporting had settled on a wrist. RotoWire reported Sept. 26 that Marshall would be Evans' next chance to play, with no team confirmation. Given Coleman's four-touchdown day, Evans returning is depth, not rescue.
One smaller thing is that Morgan Suarez went a career-high 4-for-4 on field goals against ODU and is 9-for-9 on the season, while JMU's return game produced no reported punt- or kick-return yardage for the game. The Week 2 return explosion against Wagner looks like a matchup, not a weapon. In a rivalry game that could stay close, the field-position edge is going to come from Suarez's leg rather than a house call.
The model gives JMU a 93% chance to win this one. The reason to care anyway is that a loss here would be the most expensive kind. JMU's odds of reaching the conference championship game sit at about 96% with a win and around 52% with a loss, and its playoff odds at roughly 33% versus 10%. Those are two alternative futures, not a number moving.
The rest of the board
Everything else is small, and all four are the same mechanism, national playoff competition. JMU is not playing these teams and does not share a standings ladder with them. Fewer unbeaten or one-loss Group of Five résumés ahead of the Dukes makes JMU's own at-large case marginally better. All four preferred results are underdogs, so treat them as pleasant surprises rather than plans.
Utah State at Boise State: root for Utah State
Saturday, 7:30 p.m. ET on CBSSN. The Aggies win about 11% of the time, and it is the biggest outside swing on the board at +3.4 percentage points of playoff odds. No. 22 Boise State is the most credible Group of Five résumé in JMU's way.
Liberty at Delaware: root for Delaware
Friday, 7 p.m. ET on CBSSN. Delaware is a 15% home underdog, worth +3.3 percentage points.
Temple at South Florida: root for Temple
Saturday, 7:30 p.m. ET on ESPNU. Temple wins roughly 10% of the time, worth +1.9 points. South Florida is the American contender most likely to crowd the at-large picture.
North Texas at Tulsa: root for Tulsa
Thursday, 9 p.m. ET on ESPN. Tulsa wins about 12% of the time, worth +1.7 points. Smallest item here; watch it only if you are already watching.
