LAS VEGAS — There is only so much UNLV can learn about Memphis before Saturday night.
Dan Mullen can study Kevin Decker’s offense at Old Dominion, Lance Guidry’s defenses at previous stops and the individual players Memphis assembled through the transfer portal. What UNLV cannot study is how those pieces will work together when Charles Huff sends out a team with more than 70 newcomers for the first time.
Memphis has the same problem. It knows how Mullen wants to play offensively and has a full season of Paul Guenther’s UNLV defense on film, but Jackson Arnold has never taken a snap for the Rebels, Alex Orji is healthy again and significant parts of both sides of UNLV’s roster have changed.
“There’s no film on the team we’re playing,” Mullen said this week. “I can’t watch one play of this team.”
The obvious individual matchups are easy to find. Jai’Den Thomas has to deal with J’Mond Tapp and Memphis’ front. Austin Boyd has to organize UNLV’s rebuilt offensive line. Jake Pope has to keep the Rebels’ secondary together against Decker’s spacing and tempo.
The deeper questions start with what happens before those individual battles become obvious. Three areas could determine which coaching staff gets to play the game on its terms.
1. Can UNLV Win First Down Before Memphis Gets Aggressive?
Guidry’s defense is supposed to attack. Huff described his new defensive coordinator as someone who coaches an “aggressive, attacking style,” and the two already know how they want that philosophy to work after spending the 2021 and 2022 seasons together at Marshall.
The problem for Memphis is that UNLV did some of its best work last season before defenses ever earned the chance to attack.
The Rebels produced 31 runs of at least 20 yards in 2025. Nineteen came on first down. UNLV also completed 29 passes of at least 25 yards, with 17 of them coming on first down. The Rebels averaged 5.77 yards per first-down rush and threw for 1,627 yards on first down, almost half of their season passing total.
That matters against the way Guidry wants Memphis to play.
J’Mond Tapp can disrupt an offensive line from the front, while Mike Montgomery gives Memphis a second-level defender who can pressure and play the run. Several of the Southern Miss transfers have already played together, giving Guidry experienced pieces to move around within his new defense.
Those players become much more dangerous if UNLV keeps reaching second-and-9.
Guidry can start disguising where pressure is coming from, moving Tapp and forcing Boyd to sort through more possibilities at center. Arnold or Orji then has to operate against a defense that knows the Rebels are much less likely to hand the ball to Thomas on third-and-long.
UNLV was built to avoid that problem last season. Nearly 61% of its 20-yard runs and almost 59% of its 25-yard completions came on first down. Those plays helped the Rebels avoid some of their most difficult third-down situations rather than repeatedly asking the offense to recover from being behind the chains.
Mullen now has different personnel producing those plays. Anthony Colandrea and most of last year’s top receivers are gone, leaving Arnold and Orji to work with a rebuilt receiving rotation. Thomas remains after rushing for 1,036 yards, but Memphis knows he is where the offense is likely to begin.
The matchup is not simply whether Tapp can beat a UNLV lineman. It is whether Memphis can make its aggression matter before UNLV uses that aggression against it.
A five-yard Thomas run, an Arnold keeper or one early completion into space keeps the entire playbook open. An early tackle for loss changes the next two downs and gives Guidry the game he wants.
First down may decide who gets to be aggressive.
2. Can UNLV Make Kevin Decker Earn His Explosive Plays?
Mullen has repeatedly focused on the width of Decker’s offense.
“They spread the field first,” Mullen said. “They’re gonna spread you out sideline to sideline.”
The purpose is not simply to throw short passes. Decker’s final Old Dominion offense could run the ball and generate explosive passing plays after forcing defenses to account for all of that space.
Old Dominion averaged 454.7 yards per game last season, including 238.3 rushing yards, and averaged 6.67 yards per play. Its passing game averaged 8.5 yards per attempt despite throwing only 25.5 passes per game.
That combination is important against UNLV because the difference between the Rebels’ good and bad defensive performances last season was often not how many times an opponent threw the ball. It was how damaging those throws became.
Opponents averaged 6.6 yards per passing attempt in UNLV’s 10 victories. That number jumped to 11.4 in its four losses, when opponents threw 11 touchdowns on only 96 attempts. UNLV allowed 475 yards per game and 7.95 yards per play in those losses.
That is a bigger concern Saturday than whether Air Noland or Marcus Stokes completes 65% of his passes.
Neither Memphis quarterback should have to operate like a veteran if Decker can manufacture easy explosives. The Tigers can use Dallan Hayden and the running game to pull linebackers toward the box, widen receivers toward the sideline and force UNLV’s secondary to defend more grass than it wants to.
The Rebels have to make Memphis put drives together.
UNLV was much more effective once it got opponents into third down last season, allowing conversions on only 32.94% of those attempts. The larger problem came earlier. Opponents averaged 6.26 yards per rush on first down, including 17 first-down runs of at least 20 yards.
That is where the matchup with Decker becomes dangerous. If Memphis is consistently picking up six yards on the ground, UNLV cannot spend the night sitting on deeper routes. If the Rebels start adding bodies inside, Decker gets more space outside.
Pope and the secondary have to handle the formations without giving Memphis free access downfield, but the front seven is just as important. Cam Santee, Blesyng Alualu-Tuiolemotu, Lucas Conti and the rest of the group have to make Hayden work without requiring Guenther to solve the run by pulling help away from the secondary.
UNLV does not have to eliminate every completion. It has to change what those completions are worth.
There is a major difference between Noland or Stokes completing an eight-yard pass after a long read and completing a 35-yard throw because Memphis manipulated a defender out of position. The first forces a new quarterback to do it again. The second lets Decker skip the difficult part of the drive.
That was the version of passing offense UNLV struggled to survive last season.
3. Can UNLV Steal Possessions Before Memphis Settles In?
UNLV’s defense was difficult to define last season because its biggest weakness and one of its best qualities existed at the same time.
The Rebels allowed 419.1 yards per game and 6.38 yards per play, but they also created 24 takeaways. UNLV intercepted 14 passes, recovered 10 fumbles and finished plus-seven in turnover margin. Eighteen of those takeaways came in its 10 victories.
That gave Guenther’s defense a way to survive drives that otherwise moved too easily.
Saturday presents a different opportunity. Memphis is not bringing an established offense to Allegiant Stadium. It is bringing a new coordinator, a rebuilt offensive line, new primary skill players and a quarterback who has never started a game for Memphis.
Stokes has the larger statistical résumé after throwing for 3,297 yards and 30 touchdowns at West Florida last season, but he also threw 13 interceptions on 368 attempts. Noland has spent time at Ohio State and South Carolina but enters the opener with only three college pass attempts.
Neither number predicts what happens Saturday. They do explain why an early takeaway could matter more than it normally would.
Decker’s 2025 Old Dominion offense offers some context. The Monarchs lost 23 turnovers during the regular season. In nine wins through that point, they were plus-six in turnover margin. In three losses, they gave the ball away 11 times and finished minus-nine.
The offense could produce yards without giving the ball away. It had a much harder time surviving when those possessions disappeared.
That is where UNLV can change Saturday without suddenly becoming a dominant defense.
If Memphis runs for five yards, completes an underneath pass and keeps moving the chains, Guenther may have to live with some long drives while he figures out Decker’s plan. An interception or forced fumble eliminates the need to solve every play on that possession.
It also puts pressure on a quarterback who is already learning the game in real time.
The first turnover would force Noland or Stokes to return to the field knowing one mistake has already created points or field position for UNLV. A second could change the way Decker calls the game, especially if Memphis begins protecting the quarterback instead of attacking the looks UNLV is showing.
UNLV’s own offense has a responsibility here, too. Arnold and Orji cannot give the possession back. The Rebels lost only 17 turnovers last season and finished with a plus-seven margin, part of why they could win games even when the defense allowed significant yardage.
For a Week 0 game featuring two rebuilt rosters, possessions may be more valuable than usual.
That is what separates these three matchups from the individual names that will receive most of the attention Saturday. Tapp can beat a block, Pope can break up a pass and Thomas can break a run without settling the larger questions.
UNLV has to win enough first downs to prevent Guidry from controlling the game with pressure. Its defense has to make Decker earn yards instead of giving an inexperienced quarterback explosive answers. And if Memphis gives the Rebels a chance to take the ball away, UNLV has to finish the play.
Both coaching staffs will spend the opening possessions learning what the other one actually built.
The first team that turns that information into an advantage may be the one that controls everything that follows.
