Who’s doing what so far

Duke offense (quick read): Mensah has been busy and efficient in two starts 723 yards, 5 TD, 1 INT, completing ~71% and he’s spreading it around. Oklahoma transfer Andrel Anthony is the red-zone hammer (3 TD), while Cooper Barkate has been the chain-mover (205 receiving yards). The run game has flashed chunk plays (Jaquez Moore and Anderson Castle combined 154 rush yards, 2 games), but this attack is clearly built through the air.

Tulane offense (quick read): BYU transfer Jake Retzlaff gives the Wave a true dual-threat: 277 passing yards, 2 TD, and he actually leads the team in rushing (177 yards, 2 TD). RB Zuberi Mobley added 82 on the ground at USA, and WR Omari Hayes leads with 74 receiving yards to date. Early returns say Sumrall’s bunch can run one reason their per-game split shows a strong ground lean. (A local ABC/ESPN data note has Tulane averaging ~255 rushing yards through two weeks.)

Defensive snapshots:

• Duke: Diaz’s defense is aggressive by nature, and DE Vincent Anthony Jr. has already piled up 3.5 sacks that’s critical against a QB who escapes as well as Retzlaff. The secondary is still sorting pieces with S Terry Moore (ACL) sidelined.
• Tulane: The retooled D forced five takeaways vs. Northwestern and has gotten high-volume tackling from S Jack Tchienchou (16) and ball production from DB Javion White (2 INT). The South Alabama game showed they’re not airtight yet, but the top-end havoc is there.

Matchup edges that matter to bettors

1) Duke’s pass game vs. Tulane’s disguised pressures
Mensah’s processing has been the early-season storyline; he’s delivering on time and keeping the ball out of harm’s way (just one pick). Tulane is multiple under DC Greg Gasparato and will try to squeeze throwing lanes with late rotation and bring simulated pressure to muddy Duke’s protections. If Anthony’s verticals and Barkate’s intermediate routes force Tulane into more two-high looks, Duke can live in the 6–12-yard windows all night. The flip side: if Tulane gets home with four and keeps Mensah in third-and-long, those field-goal drives stack up.

2) Tulane’s run rate vs. Duke’s front seven
This feels like the lever. Retzlaff plus a deep RB room lets Sumrall lean on QB run + gap schemes and stress edges. Duke’s best answer is penetration Anthony Jr. knifing in, LBs scraping downhill and winning early downs. If Tulane is on schedule, they’ll control tempo, protect their defense, and keep Mensah watching. The ABC/ESPN data blip (Tulane around 255 rush YPG) squares with the film: they’re a ground-first outfit right now.

3) Hidden yardage: turnovers & special teams
Tulane’s Northwestern tape (five takeaways) and the way Duke unraveled vs. Illinois underscore it: early-season variance often comes from giveaways. If either team finishes -2 in turnover margin, it probably decides the bet more than any schematic edge. Tulane’s Patrick Durkin (5/5 FGs, long 50) has been money; Duke’s Todd Pelino (3/4 FGs) is steady, too. In a one-score spread, the kicker edge is a real thing.

Injuries & notes to monitor

• Duke: Safety Terry Moore (knee) remains out. That’s a leadership hit on the back end for Diaz’s defense.
• Tulane: RB Maurice Turner (ankle) and WR Jha’Quan Calloway have been listed as questionable on some injury boards this week. Depth is decent, but either absence trims a package or two.

Market view & my numbers

Between ESPN Analytics (~72% Tulane) and a consensus -3 to -3.5, oddsmakers are effectively saying Tulane’s a hair above a field goal better at home. Given the matchup Tulane’s run game against a Duke defense that just got stress-tested by Illinois and the heat/humidity angle at Yulman on a long Duke travel day, that checks out. Meanwhile, Duke’s offense is lively enough that you don’t want to lay a big number; Mensah can keep this within a score late.

On totals: Duke game totals have been 62 and 64; Tulane’s were 26 and 64. That’s an average of ~54 across the four combined samples right on top of the current number. If Tulane dictates with the ground game, clock churn could cap possessions; if Duke hits explosives early, we tilt to the high 50s. With the board split 52.5–53.5, I slightly prefer Over 52.5 (but would pass at 53.5 unless you price it fairly).

The pick

Tulane -3 (playable to -3.5, or moneyline if you’re allergic to hooks). I trust Sumrall’s run game and a modest defensive edge at home. Retzlaff’s legs are a headache in the low red zone, and Tulane’s special teams have been sharper through two weeks. Duke will move it Mensah’s too poised not to but the on-schedule runs and a late Tulane drive tilt it.

Projected score: Tulane 31, Duke 27.
If you can still find 53, I’d lean Over; at 53.5, the value is thinner and I’d keep it smaller.
