Built. Broken. Rebuilt, Again. What UNLV’s Offense Proves, and What Dan Mullen’s Walking Into

(Credit - )

Two years ago, UNLV was a slow, predictable, and uninspiring program, constrained by poor schemes and even worse execution. Today, it’s nationally interesting, not because of its tradition, but because something was built, fast.

This isn’t about vibes. This is about volume. About pressure. About what happens when you stop waiting for balance and instead shove the throttle down and dare defenses to keep up.

Let’s talk about what Barry Odom and Brennan Marion did. And what Dan Mullen’s walking into now that it’s all his.

UNLV’s offense didn’t gradually evolve. It whiplashed from Marcus Arroyo’s stuck-in-neutral playbook to Barry Odom’s high-octane tempo. It wasn’t just new energy. It was a new identity.

And Marion made the goal clear from Day One.

“We want to play fast,” Marion told the Las Vegas Sun in spring 2023. “It doesn’t stop. It’s every day. We don’t ever take a break. We’re always gas.”

That wasn’t just hype. That was a mission statement.

In 2021, UNLV ran 726 total offensive plays. In 2022, they ran 763 both under Arroyo.

Under Odom and Marion in 2023? That number jumped to 932. And in 2024? 942.

That’s 216 more plays than the 2021 offense, the equivalent of three extra games of offense in one season. That’s not tempo for tempo’s sake. That’s calculated aggression. That’s how you stress defensive personnel, disguise looks, and force miscommunications.

Marion’s Go-Go offense didn’t just run fast, it ran smart. Every motion, formation, and misdirection was designed to create conflict. And it worked.

UNLV’s total offensive yards (including postseason):

Under Arroyo, UNLV hovered just under 4,000 yards per year. Under Odom and Marion, it leaped to nearly 5,800 — a 50% increase in output.

Seven games in 2024 topped 450 yards. Three blew past 500. And in Week 2 against Utah Tech, UNLV detonated for 694 yards, the most in modern program history.

You don’t luck into 694 yards. You build toward it.

Here’s what UNLV did, week by week:

It wasn’t always smooth. There were valleys, especially late in the year. But when this system clicked, it didn’t just score. It overwhelmed.

Let’s lay it out plainly:

Arroyo’s teams played not to lose. Odom’s teams played to burn you. They created space, tempo, and conflict. The quarterback wasn’t just a facilitator; he was a weapon. Marion’s formations were unbalanced, unpredictable, and hard to scout. His receivers ran in motion, out of bunches, with intentional chaos.

UNLV went from one of the least watchable offenses in college football to a system where even the tight ends mattered.

From the Las Vegas Sun and Campus2Canton reporting, Marion made his vision crystal clear:

The Go-Go offense was built on triple-option spacing, spread tempo, RPOs, two-back sets, and deception. It was one of the most innovative and entertaining systems in the country.

Let’s be real: this system is gone.

Brennan Marion is now the head coach at Sacramento State. Barry Odom is at Purdue. The staff that built the Go-Go identity is out. The philosophy? Out.

Dan Mullen has his ideas and playbook. Expect a more traditional spread, quicker reads, West Coast principles, and a quarterback-driven decision tree. Mullen’s building will likely be more structured, more sustainable, and less chaotic.

But here’s the problem: UNLV just ran 942 plays and racked up nearly 6,000 yards. That’s the new normal. That’s the baseline.

And anything slower, safer, or flatter will appear to be regression, whether it is or not.

This isn’t about preserving what Odom and Marion built. It’s about understanding why it worked and knowing that it raised the stakes.

Odom didn’t get four years. He got two. And he made them count. He rebuilt the offense from nothing, took it to the title game twice, and made UNLV matter again.

Mullen now steps in with more resources, more buy-in, and more pressure.

You don’t get four-year rebuilds anymore. You get transfer windows, raised expectations, and fans who know the difference between dangerous and vanilla.

Dan Mullen’s job isn’t to mimic 2024.

It’s to grow from it.

Let’s see if the gas pedal stays down or if UNLV slips back into cruise control.

This is just the beginning.

This piece kicks off a full series I’ll be writing as we head into the 2025 UNLV football season, breaking down everything from offensive identity to coaching decisions, game previews, and the storylines that actually matter.

Coverage will continue throughout the year, no fluff, no filler, just real analysis from the ground up.

Let’s get to work.
