LAS VEGAS — Anthony Colandrea and Jackson Arnold have taken almost completely different routes to nearly the same place through their first two games at UNLV. Colandrea accounted for 560 yards of total offense against Idaho State and Sam Houston to begin the 2025 season. Arnold has produced 550 against Memphis and Hawai‘i this fall. Ten yards separate them through two games. Arnold has accounted for five touchdowns, one more than Colandrea had at the same point, and has yet to turn the football over. The similarity mostly ends there. Colandrea completed 34 of 44 passes for 444 yards, three touchdowns and one interception while rushing 19 times for 116 yards and another score. Arnold is 33 of 55 for 407 yards and two touchdowns while adding 143 net rushing yards and three touchdowns on 37 official carries. Colandrea completed 77.3 percent of his passes and averaged 10.1 yards per attempt. Arnold is completing 60 percent and averaging 7.4. The totals make the quarterbacks look almost interchangeable through two weeks. The way UNLV has had to get those yards does not.
That is a better way to view the comparison than asking whether Arnold has reproduced what Colandrea did a year ago. Dan Mullen spent fall camp resisting that idea. Colandrea had his own strengths. Arnold had his. Alex Orji had his. Mullen’s job was to construct the offense around whichever quarterback was on the field rather than force the next one into the same version of it. “You have to be yourself,” Mullen said during camp. “Sure, you can take things and we do different things that people have done in the past. But ultimately, we as coaches have to enhance those guys and play to their strengths more than anything.” Colandrea’s first two games eventually became the opening evidence that Mullen had found an offense that suited him.
It did not immediately look that way against Idaho State. UNLV trailed 10-0 after the first quarter and 17-14 at halftime before rallying for a 38-31 win. Colandrea completed 15 of 21 passes for 195 yards and a touchdown, but some of his most damaging work came on the ground. He ran 13 times for 93 net yards, including a 37-yard gain, and finished with 288 yards of total offense. Jai’Den Thomas carried much of the rest of the rushing load, finishing with 147 yards and three touchdowns. Orji also remained part of the offense, completing all three of his passes for 37 yards and scoring the eventual game-winning touchdown on an 11-yard run. UNLV finished with 532 yards, including 300 rushing, and averaged more than 7.8 yards per play despite needing four fourth-quarter interceptions from the defense to complete the comeback.
Mullen came away from that opener encouraged by the way both quarterbacks managed their first game in his system. “I thought they played fantastic,” Mullen said the following week. He pointed to their willingness to take available throws, check the football down and avoid turning every snap into something bigger than it needed to be. Colandrea had not yet become the unquestioned centerpiece of the offense. Mullen still planned to use both quarterbacks and was learning how what he had seen in practice would translate once the season started. Six days later, Colandrea made the picture much clearer.
Colandrea completed 19 of 23 passes for 249 yards and two touchdowns at Sam Houston, added 23 rushing yards and scored again on the ground. He completed 82.6 percent of his attempts and averaged 10.8 yards each time he threw. Jaden Bradley caught six passes for 125 yards, including a 43-yard touchdown on UNLV’s opening drive, and Colandrea later found DeAngelo Irvin Jr. for another score. UNLV needed only 56 offensive plays to gain 404 yards, averaged 7.2 yards per snap and won 38-21. Mullen had given Colandrea a specific standard as the offense developed. “You have to be close to a 70 percent completion guy,” Mullen recalled telling him. Colandrea was well beyond that mark through two weeks. His 77.3 percent completion rate eventually came down, but not by much. He finished the season completing 65.9 percent of his passes for 3,459 yards and 23 touchdowns and became the Mountain West Offensive Player of the Year.
The first two games had already shown why the offense could work around him. UNLV gained 936 yards on 124 plays against Idaho State and Sam Houston, an average of about 7.5 yards per snap. The Rebels produced 481 passing yards and 455 rushing, recorded 45 first downs and scored 76 points. One touchdown at Sam Houston came on Aamaris Brown’s 52-yard interception return, leaving the offense responsible for 69. Colandrea accounted for roughly 60 percent of UNLV’s total offense despite Orji still holding a meaningful role. Arnold has carried an even larger percentage of the offense this season, but the surrounding efficiency has been different.
His debut against Memphis initially looked capable of resembling Colandrea’s early passing production. Arnold completed 17 of 21 passes for 203 yards before halftime as UNLV took a 14-7 lead. He finished 25 of 37 for 291 yards and two touchdowns, connected with Tavian McNair for a 38-yard score and later found Kayden McGee for another from 22 yards. Arnold also ran for a touchdown and finished with 345 yards of total offense after adding 54 net rushing yards. UNLV gained 460 yards, recorded 23 first downs and possessed the football for 35 minutes, 9 seconds. Most of those numbers would normally point toward a win, but the problem was what happened around them.
Memphis sacked Arnold six times, all after halftime, and UNLV scored only once after the break. The Rebels converted three of 15 third downs and two of five fourth downs. They reached the Memphis red zone four times, scored touchdowns twice and came away empty after a fourth-down failure and a missed field goal. “The game came down to red-zone scoring,” Mullen said afterward. Arnold had played well enough for Mullen to largely abandon the quarterback rotation he originally planned. The offense still did not finish enough of the opportunities Arnold helped create.
A week later, Mullen did not ask him to solve the same problem the same way. UNLV went to Hawai‘i and cut Arnold’s pass attempts from 37 to 18. He completed eight for 116 yards, numbers that look modest until they are placed next to everything else the Rebels did. Arnold ran 16 times for 89 net yards and scored twice. Thomas carried 20 times for 143 yards and another touchdown. UNLV used more two- and three-tight-end personnel, stayed out of many of the obvious passing situations that had hurt it against Memphis and finished with 248 rushing yards in a 21-6 win. “We wanted to try to control the ground game a little bit,” Mullen said afterward. “I thought we were able to do that.” That adjustment is part of why Arnold’s 550 yards require more context than the number alone provides.
Arnold is 37 passing yards behind Colandrea’s two-game total despite attempting 11 more passes. His completion percentage is 17.3 points lower. His yards per attempt are down 2.7. Colandrea generated 444 passing yards on 44 attempts. Arnold has needed 55 to reach 407. The rushing side moves the comparison in the other direction. Arnold has 27 more net rushing yards, two more rushing touchdowns and nearly twice as many official carries. Even after removing sacks from both quarterbacks’ totals, Arnold has 30 non-sack rushing attempts through two games compared with 15 for Colandrea. UNLV has deliberately put the football in Arnold’s hands as a runner far more often.
The sack totals help explain why his rushing line needs to be separated. Colandrea was sacked four times through his first two games. Arnold has already been sacked seven times, six against Memphis and one at Hawai‘i. College football charges sack yardage against individual rushing totals, so Arnold’s 37 carries for 143 yards do not fully represent how productive he has been when UNLV has intentionally used him as a runner. Arnold has gained 207 yards on his recorded rushing attempts before 64 yards in losses are subtracted. Against Memphis, his official line was 21 carries for 54 yards. He actually gained 108 before losing 54, much of it on sacks. Hawai‘i provided the cleaner look: 16 carries, 89 net yards, two touchdowns and one sack. That distinction matters because the quarterback run is not simply something Arnold has created when plays break down. It has become part of how UNLV is moving the football.
Where Arnold has been cleaner than Colandrea was through the same point is with turnovers. He has thrown 55 passes without an interception, and UNLV has not lost a fumble through two games. Colandrea threw an interception at Sam Houston, while Orji lost a fumble against Idaho State. The Rebels had two giveaways through two games last season. They have none this year. That has not translated into more points because UNLV has lost possessions in different ways. The six sacks against Memphis created long-yardage situations, failed fourth downs ended drives and scoring opportunities disappeared without points. Arnold has avoided giving opponents the short fields that often make those problems worse, but avoiding turnovers has not been enough to offset everything else.
The larger team numbers show how different the two offensive starts have been despite nearly identical quarterback production. UNLV has gained 824 yards on 140 plays this season, 112 fewer yards than it had through two games last year despite running 16 more snaps. The Rebels averaged about 7.5 yards per play during Colandrea’s first two games. They are at 5.9 through Arnold’s. They had 45 first downs then and have 41 now. The 2025 offense converted eight of 21 third downs and both fourth-down attempts. This season, UNLV is 10 of 30 on third down and two of seven on fourth. The Rebels have actually possessed the ball longer this season, 63:04 compared with 60:54 through two games last year. They have simply produced fewer yards and fewer points from those possessions.
Arnold’s share of those yards is another difference. His 550 yards account for about 67 percent of UNLV’s 824 total yards. Colandrea’s 560 represented just under 60 percent of the Rebels’ 936 through two games last season. Some of that comes from the quarterback rotation Mullen was still using in 2025, and some comes from Arnold becoming such a significant part of this year’s rushing attack. He has thrown every quarterback pass against Memphis and Hawai‘i and accounted for nearly 44 percent of UNLV’s official rushing attempts. The two quarterbacks may be separated by only 10 total yards, but UNLV has needed Arnold to handle a greater portion of the offense to reach almost the same individual production.
The red-zone comparison points in the same direction. UNLV reached the red zone 11 times against Idaho State and Sam Houston last season, scoring on eight possessions with six touchdowns and two field goals. The Rebels have reached it only six times this year and scored on four, all touchdowns. The current 66.7 percent red-zone touchdown rate is actually better than the 54.5 percent rate through two games last season. The issue is getting there. Colandrea’s first two offenses created five more red-zone possessions. Arnold’s offense has been more likely to score a touchdown once it reaches that part of the field, but it has not reached it nearly as often.
There are limits to treating any of this as a direct quarterback comparison. Colandrea opened against an FCS Idaho State team before playing Sam Houston. Arnold began with Memphis and then traveled to Hawai‘i for an early Mountain West road game. UNLV also lost starting center Austin Boyd during the Memphis game and had to reconstruct the middle of the offensive line before going to Honolulu. The receiving corps is different, Corey Dennis has a larger role in the offense and Mullen has another year of information on Thomas and the rest of the returning personnel. Two-game statistics cannot separate either quarterback from all of that, but they can show how differently Mullen has built the production around them.
Colandrea arrived as an experienced, improvisational quarterback whose willingness to create could occasionally work against him. Mullen spent much of the 2025 preseason teaching him that every snap did not require something extraordinary and emphasizing the value of completing the routine throw. By the end of his second game, Colandrea was completing more than 77 percent of his passes, averaging more than 10 yards per attempt and still giving UNLV enough on the ground to make defenses account for him. Arnold brought a different set of concerns. His arm talent and running ability were already obvious from his previous stops, but sacks and inconsistent passing stretches had followed him. Mullen did not hand him Colandrea’s offense and demand the same statistical line.
The first two games have instead shown a willingness to move between very different plans. Arnold threw 37 times against Memphis when UNLV needed him to create through the passing game. A week later, he threw only 18 times as the Rebels leaned on heavier personnel, Thomas and Arnold himself to control Hawai‘i on the ground. The adjustment worked well enough to win, but it still left UNLV with a quarterback who has nearly matched Colandrea’s raw production without matching the efficiency of the offense Colandrea directed through two weeks.
Arnold has protected the football better and carried a much larger portion of the running game. Colandrea completed passes at a higher rate, produced more yards on fewer opportunities and played within an offense that created more red-zone trips, more points and more yards per snap. UNLV was 2-0 after Colandrea’s first two games. It is 1-1 after Arnold’s. That does not mean Arnold needs to become Colandrea. It means UNLV needs to get more from the possessions already running through him.
Arnold has 550 yards of total offense, five touchdowns and no turnovers. He is 10 yards behind where the Mountain West Offensive Player of the Year stood through two games last season. The individual production is almost identical. The way UNLV is getting there, and what the offense has produced around it, is not.
