This is the Depth Dossier: the UNLV Rebels, Week 7.

UNLV had Air Force beat, led them in the fourth quarter, and still walked away with a 41 to 31 loss, which makes this the third straight game where the Rebels' second half has completely fallen apart.

Here's how it unfolded. UNLV was up 24 to 20 heading into the fourth quarter, riding quarterback Jackson Arnold's 246 passing yards and two touchdown throws, plus running back Kayden McGee's 99 total yards and two scores. The Rebels looked like they were about to pull off the upset. Then wide receiver Troy Stellato fumbled after picking up a first down, Air Force scored off the turnover, and the Falcons reeled off 21 unanswered points to close it out 41 to 31. UNLV's defense simply couldn't get off the field or slow down Air Force's running game in that final quarter. The Rebels ran for 130 yards themselves, but a turnover margin of minus two sank them against a team that didn't give the ball away once.

The box score shows a ten-point loss, but it doesn't tell you UNLV led with fifteen minutes to go, or that this is the third time in three losses this season the fourth quarter has buried them. Across those three losses, to Memphis, North Texas, and now Air Force, UNLV has been outscored 72 to 24 in the second half. That's not a fluke anymore, and coach Dan Mullen knows it.

The turnovers tell you exactly how this game flipped. Arnold threw an interception in the second quarter that gave Air Force an opening, but the real dagger was Stellato's fumble in the fourth, which Air Force turned into points to make it 34 to 24 before piling on more to make it 41 to 24. Air Force, meanwhile, didn't turn the ball over a single time. Mullen pointed right at that minus-two turnover margin after the game. The Falcons also controlled the clock, holding the ball for over 35 minutes to UNLV's under 25, and piled up 448 total yards to UNLV's 376.

There were bright spots. Backup punter Ethan Schwartz drilled a school-record 60-yard field goal right before halftime, putting UNLV up 17 to 13 and coming within a yard of the Mountain West record. UNLV punted just once all game, and not until the fourth quarter, the program's first game without a first-half punt since 1985. Running back Jai'Den Thomas, known as "Jet," crossed 3,000 career rushing yards, becoming just the fifth Rebel to hit that mark. And safety Jake Pope racked up 15 tackles, though that number gets overshadowed by the defense's bigger problem, containing Air Force's option attack.

Now let's get into who's moving and who isn't.

No injuries have been reported from this game, so health isn't the story here. The real issue is that fourth-quarter collapse happening for a third straight week, and that falls on how the defense responds to long drives, not any kind of personnel shakeup. Pope's big tackle total keeps him central to that unit as they search for answers against option-style rushing teams.

On offense, nothing's changing at quarterback or running back. Arnold's two-touchdown day and Thomas's milestone performance both lock in roles that were already set. The one name worth watching is Stellato, whose fumble turned a close game into a blowout. How the coaching staff handles his touches going forward is worth tracking, though nothing's been reported there yet. Schwartz's record-setting kick is the clearest specialist storyline, since a 60-yard field goal from a backup punter could complicate the kicking rotation, though again, no formal change has been announced.

With the second-half trend now three games deep, the real question for UNLV isn't who starts next week. It's whether this same group can finally hold onto a lead.
