Through two parts of this series, we’ve broken down the architecture of Dan Mullen’s offense: how it uses formation, spacing, and geometry to attack defenses through the run and pass. But the system alone doesn’t win games; quarterbacks do.
And no one develops quarterbacks quite like Dan Mullen.
Quarterback-Friendly, Not Quarterback-Dependent
There’s a misconception that Mullen’s offense requires a specific prototype, a mobile, dual-threat battering ram like Tim Tebow or Nick Fitzgerald. In truth, what defines his success is adaptability.
He builds the offense around his quarterbacks, not the other way around. That’s what allows him to win with a statuesque pocket passer like Kyle Trask one year, and then run a zone-read-heavy, downhill attack with Nick Fitzgerald or Dak Prescott the next.
The foundation of his system gives quarterbacks pre-snap clarity:
Box count determines run/pass
Safety depth dictates where the ball should go
Leverage reads decide when to pull, pitch, or throw
Everything is designed to facilitate quick and clean decisions.
The Track Record Speaks
Let’s break down the quarterbacks Mullen has developed, using the 12 signal callers who started at least six games under Mullen. The results are staggering:
Dak Prescott: Transformed from a three-star recruit into a two-time Pro Bowler and one of the NFL’s most efficient quarterbacks. Fourth all-time in SEC history in both total yards (11,897) and total touchdowns (114).
Tim Tebow: National titles. A Heisman Trophy. College football icon. Mullen built the original modern spread around his strengths and won big.
Alex Smith: Two years under Mullen at Utah turned Smith into the No. 1 overall pick in 2005 and a 3-time Pro Bowler.
Kyle Trask: Never started a high school game. Under Mullen, he became a Heisman finalist, broke Florida’s passing records, and was drafted by the Buccaneers.
Nick Fitzgerald: Not an elite passer, but still holds the SEC record for career QB rushing yards (3,607). Mullen adapted the offense to fit what he did best.
Whether it was Tyler Russell setting passing records at Mississippi State, Feleipe Franks reviving his career, or Josh Harris accounting for 41 TDs at Bowling Green, the pattern is clear: Mullen finds what you can do, and he builds the system around that.
What This Means for UNLV in 2025
This matters more than ever for a team like UNLV, which enters fall camp with questions at quarterback. There is no Kyle Trask on this roster, and that’s fine. There doesn’t need to be.
Mullen has shown he can win with pure athletes (Fitzgerald), smart game managers (Relf), high-efficiency passers (Trask), and elite processors (Prescott, Smith). His job is to identify the strengths of his quarterback room and make the game easier.
So what will that look like?
If UNLV’s QB1 is mobile, expect heavy use of zone read, QB counter, and speed option, paired with deep shots off RPOs.
If the quarterback is a thrower, look for vertical layering concepts, clear reads off motion, and four-verticals variants from 3x1 sets.
If there's a young QB in the room? Mullen will likely use tags, tempo, and simplified reads to build confidence early.
UNLV’s Next QB: Who Fits the Mold?
The question heading into August camp isn’t “who starts?” It’s “who fits best in Mullen’s decision-making framework?”
Quarterback in this system isn’t about highlight plays. It’s about processing: read the box, check the safeties, trust the scheme. Whoever handles that the fastest is going to play. Whoever understands leverage and how to throw “where they ain’t,” as former OC Brian Johnson once said, is going to thrive.
And in the long run? That quarterback’s growth will be Mullen’s next success story.
Up Next: Part 4 — From Arroyo to Odom to Mullen: How UNLV’s Offense is Evolving
In the next installment, we’ll shift from theory to contrast. What does Mullen’s offense look like next to what UNLV ran under Marcus Arroyo and Barry Odom? How will tempo, play design, and quarterback usage change, and what carries over? From plodding power sets to frantic spread tempo, we’ll explore how the Rebels are redefining their offensive identity in 2025.
