LAS VEGAS — One of the more confusing parts of UNLV’s offensive start is that one of the foundations of Dan Mullen’s offense is still working. The Rebels are getting what they want on first down. Through two games, UNLV is averaging 5.87 yards per first-down rushing attempt, slightly better than the 5.77 it averaged over the entire 2025 season. The difference is small and the current sample is only two games, but first down was one of the places last year’s offense consistently created an advantage. Nineteen of UNLV’s 31 runs of at least 20 yards came on first down in 2025, while 17 of its 29 completions of at least 25 yards also came there. The Rebels frequently avoided having to rescue possessions on third down because they did enough damage before the defense could force them into one.
The Rebels can still create that advantage. What has changed is how often the offense has been able to preserve it for the rest of the possession. The Rebels have gained 824 yards on 140 plays through two games, averaging 5.9 yards per snap. Through the same point last season, they had 936 yards on only 124 plays, about 7.5 per snap. UNLV has actually possessed the football longer this year, 63 minutes, 4 seconds compared with 60:54 against Idaho State and Sam Houston last season, yet it has run 16 more plays and produced 112 fewer yards. The scoring difference is even larger. UNLV has 42 points through two games. It had 76 at the same point last season, and even removing Aamaris Brown’s interception return at Sam Houston leaves the 2025 offense with 69.
That difference extends beyond Jackson Arnold completing fewer passes than Anthony Colandrea did. UNLV has punted 12 times this season, six against Memphis and six at Hawai‘i. It punted six times total through its first two games last year. The 2025 offense was hardly flawless in August. Idaho State forced four punts, recovered a UNLV fumble and watched the Rebels miss two field goals. The difference was that UNLV produced enough explosive plays and created enough additional scoring opportunities to survive those wasted possessions. Through two games this season, the margin for a stalled series has been much smaller.
First-Down Success
Hawai‘i may be the clearest example because UNLV’s first-down production was almost absurd. According to The Scarlet Standard’s charting, the Rebels ran 27 first-down plays for 245 yards, an average of 9.1 yards per snap. Twenty were runs, and those averaged 8.2 yards. Jai’Den Thomas’ 50-yard touchdown late in the fourth quarter inflates that figure, but not enough to explain it away. Remove the touchdown and UNLV still gained 195 yards on its other 26 first-down snaps, 7.5 per play. Remove it from the rushing total and the other 19 first-down runs still averaged roughly six yards. For much of the night, the Rebels were creating exactly the down-and-distance Mullen wants.
The drive chart tells a much different story. UNLV scored touchdowns on two eight-play possessions in the first half, but its other drives before halftime ended with three punts and two failed fourth downs. The Rebels punted on both of their meaningful third-quarter possessions and twice more in the fourth before Thomas finally broke the 50-yard touchdown run. UNLV finished with 248 rushing yards and averaged six yards per play, yet six possessions ended with punts and two more ended on downs. The Rebels were consistently winning individual snaps without consistently turning those wins into completed drives.
That is where first-down efficiency and drive efficiency have separated. A productive first down matters only if the offense keeps the advantage it creates. UNLV has too often moved itself ahead of schedule and then needed to win the possession again after a penalty, sack or missed opportunity erased the favorable situation. What should become second-and-short turns into long yardage. A productive run disappears because of a flag. One negative play turns a manageable series into an obvious passing situation, and by the time third or fourth down arrives, the work done on first down no longer matters.
UNLV’s first possession of the third quarter at Hawai‘i showed how quickly that can happen. A defensive pass interference penalty moved the ball to the UNLV 33. Thomas followed with eight yards on first down, exactly the type of play that should have created second-and-2, but a holding penalty erased it and instead put UNLV at first-and-20. Arnold threw incomplete, another eight-yard run was erased by offsetting penalties, Thomas gained six and Arnold’s third-and-14 pass to Thomas fell incomplete under pressure. A possession that included the type of first-down run UNLV wants ended with a punt from its own 29.
Third-Quarter Problems
The third quarter in Honolulu needs to be separated from what happened against Memphis because the Rebels reached the same result in two very different ways. Hawai‘i opened the half with a 13-play possession that consumed 5:31. UNLV got the ball for 1:26, punted, and Hawai‘i immediately followed with another 14-play drive that lasted 6:31. By the time the Rebels took possession again with 1:32 left in the quarter, their offense had held the football for only 1:26 of the previous 13½ minutes. UNLV needed to extend its first possession, but the lack of third-quarter production was not solely an offensive play-calling issue. Hawai‘i simply kept the ball away from it.
Memphis was different because UNLV had opportunities to control the second half and gradually became more dependent on Arnold as the protection deteriorated. A Scarlet Standard review of the play-by-play found 25 dropbacks in each half even though UNLV ran five fewer plays after halftime. Designed runs dropped from 17 in the first half to 12 in the second. Thomas and the rest of the backfield had helped balance the offense while Arnold completed 17 of 21 passes for 203 yards before halftime. As Memphis began winning against the protection after the break, UNLV put more of the game on its quarterback rather than less.
The opening third-quarter possession worked. After Memphis tied the game, Arnold ran for 54 yards, Thomas followed with gains of nine and two, and Arnold eventually found Kayden McGee for a 22-yard touchdown. Thomas had been targeted on the opening snap and carried twice on the drive, but he did not record another offensive touch during the quarter. UNLV had three possessions remaining in the period and scored on none of them.
It would be too simple to reduce the problem to giving Thomas more carries. Jaylon Glover immediately provided another productive rushing answer on the next possession, gaining four yards before breaking a 44-yard run to the Memphis 27. The drive changed on the next snap when J’Mond Tapp and Elijah Kinsler sacked Arnold for a six-yard loss. Glover was stopped on second-and-16, Arnold threw incomplete on third down and his fourth-down completion to McGee gained 15 yards when UNLV needed 16. Two Glover carries had moved the offense 48 yards, but one negative play changed the rest of the series.
The next possession followed the same pattern. Arnold opened it by finding Peyton Zachary for 14 yards and a first down. UNLV then went incomplete pass, incomplete pass, sack and punt. Memphis had not sacked Arnold before halftime. It got him twice in the third quarter and four more times in the fourth. The concern was not simply UNLV’s run-pass ratio. Memphis was beginning to dictate the game through negative plays, and the Rebels became increasingly quarterback-dependent at the same time their protection was breaking down. Arnold could solve one problem himself, as his 54-yard run showed, but repeatedly asking him to recover from second-and-long and third-and-long gave Memphis the obvious passing situations its defensive front wanted.
That helps explain why the third-quarter scoring difference from last season stands out even after only two games. UNLV scored 10 points in the third quarter against Idaho State and seven at Sam Houston to begin 2025. It has scored seven total this season, all on Arnold’s touchdown pass to McGee against Memphis. Against Idaho State last year, the Rebels opened the second half with a 93-yard touchdown drive and followed it with a 71-yard possession that ended in a field goal. At Sam Houston, their first second-half possession went 67 yards in five plays for a touchdown. The 2025 offense did more than start possessions well. It finished enough of them before the defense could force the game into obvious passing situations.
Conversion Volume
That ability eventually became one of the strengths of UNLV’s 10-win season. The Rebels converted 45.6 percent of their third downs in 2025 and 56.5 percent of their fourth downs. They scored on 53 of 60 red-zone possessions, an 88.3 percent rate, and 42 of those trips became touchdowns. UNLV averaged 34.1 points and 6.8 yards per play while consistently avoiding the kind of repeated decision points that have become much more common through the first two games this season.
Through two games this year, UNLV is 10 of 30 on third down, 33.3 percent, and two of seven on fourth down, 28.6 percent. Through the same point last season, the Rebels were eight of 21 on third down and perfect on their two fourth-down attempts. The third-down percentages themselves are not dramatically different yet. The volume is. UNLV has already faced nine more third downs and five more fourth downs than it had through two games last season.
That is another way of seeing the same problem. The offense is spending more of each possession at a decision point instead of converting early-down success into a new set of downs before third or fourth down becomes necessary. The Hawai‘i game showed the contradiction as clearly as anything UNLV has put on film. The Rebels could average more than eight yards per first-down run and still punt six times because too many possessions required another conversion later in the series.
The first-down production therefore is not misleading. It is real. It simply has not been carrying far enough into the possession.
Red-Zone Opportunities
The red-zone numbers require a similar distinction. UNLV has scored touchdowns on four of six trips inside the 20 this season. Its 66.7 percent touchdown rate is actually better than the 54.5 percent rate through two games last year, when six of 11 red-zone possessions became touchdowns. The current rate is also close to the 70 percent touchdown rate the Rebels posted over the full 2025 season. If the discussion were limited only to what happens after UNLV crosses the 20, there would not be much reason for concern.
The difference is opportunity. Last year’s offense reached the red zone 11 times through two games. This one has reached it six. Memphis made the missing opportunities especially damaging because UNLV went two-for-four in the red zone, missed a field goal at the end of the first half and later allowed Arnold to be sacked on fourth down with an opportunity to retake the lead. Mullen went directly to it afterward.
“The game came down to red-zone scoring, which is a huge part of playing to win,” Mullen said. “If you look at that game, when we had several different red-zone opportunities, we came up short on fourth down twice and missed a field goal in the red zone.”
Hawai‘i corrected the finishing part of that problem. UNLV went two-for-two in the red zone and Arnold completed both possessions with rushing touchdowns. What the Rebels did not correct was how often they got there. They gained 364 yards and averaged six yards per play but reached the red zone only twice. Thomas’ 50-yard touchdown was valuable in part because it allowed UNLV to bypass everything else that had been interrupting possessions and go directly from midfield to the end zone.
The distinction matters because UNLV does not yet have a red-zone touchdown problem. It has a red-zone opportunity problem. The Rebels are finishing enough possessions once they get close. They are not getting close often enough.
Arnold’s Workload
Arnold’s individual production helps explain why the offense can look more functional statistically than it has possession by possession. Colandrea produced 560 yards of total offense through his first two games in 2025. Arnold has 550. Colandrea completed 34 of 44 passes for 444 yards, while Arnold is 33 of 55 for 407. Arnold has made up much of the difference with 143 net rushing yards and three rushing touchdowns, and he has yet to throw an interception.
The larger offensive picture is much different. Colandrea accounted for just under 60 percent of UNLV’s 936 yards through two games last season. Arnold has accounted for roughly two-thirds of the Rebels’ 824 this year. He has also taken seven sacks and logged 37 official rushing attempts. His running ability has been one of the best parts of the offense, particularly at Hawai‘i, but UNLV has already needed considerably more from him while producing fewer yards and fewer scoring opportunities overall.
That workload is not automatically a problem. Arnold’s ability to run changes the numbers for a defense and gives Mullen and Corey Dennis an option the offense can build around rather than merely use when a play breaks down. The concern is what happens when UNLV needs Arnold to be the answer to several different problems on the same possession. Once a penalty or sack creates long yardage, the designed quarterback run becomes less threatening, Thomas becomes easier to remove from the equation and the defense can devote more of its attention to the pocket.
Arnold explained part of that difference after Hawai‘i. Memphis had been able to create more pressure once UNLV fell into obvious passing situations, while the Rebels avoided many of them a week later.
“I think situationally, honestly, is the biggest difference,” Arnold said. “Us just being able to manage the game and staying ahead of the chains really kind of prevented them from pressuring us and getting back in the backfield.”
The first-down numbers say UNLV did exactly that in Honolulu. The Rebels consistently created manageable situations. The next step is making that advantage last through the rest of the possession rather than asking Arnold to recreate it after something goes wrong.
North Texas Test
There are reasons not to make the comparison with 2025 absolute. Colandrea’s first two games came against an FCS Idaho State team and Sam Houston. Arnold opened against Memphis and then traveled to Hawai‘i for a conference road game. Starting center Austin Boyd was injured late against Memphis and did not play in Honolulu. The receiving corps and offensive line have changed, and Dennis has a larger role in an offense still determining how its pieces fit together. Two games can identify a problem without proving it will remain one.
They do identify a fairly clear issue before North Texas. UNLV does not need to rediscover how to get five or six yards on first down. It is already doing that. Its 5.87 yards per first-down rush are slightly ahead of last season’s rate, and the Hawai‘i game showed how productive the offense can be before a series reaches its decision point. What the Rebels need is to stop surrendering those advantages through sacks and penalties, reduce how often third and fourth down decide possessions and turn more of their early-down production into trips inside the 20.
North Texas should provide a useful test because the Mean Green can create the type of situations that have caused UNLV problems. Matt Powledge’s defense can change fronts and pressure pictures, making communication especially important with Boyd still unavailable. If UNLV keeps Thomas and Arnold in favorable down-and-distance situations, the Rebels can force North Texas to continue respecting both runners while also attacking a secondary already dealing with injuries. If the Mean Green can create the negative plays Memphis found after halftime, the same offense becomes much easier to defend.
That is why the first-down numbers matter without being enough on their own. They show UNLV already has a way to create the situations it wants. The problem comes when the Rebels give those situations back before the possession has produced anything.
Last year’s offense often won first down and never had to win the possession again. Through two games this season, UNLV has too often created the advantage and then given itself another problem to solve before the drive reaches the end zone.
