Week 2 of the 2026 college football season serves up a MASSIVE Big 12 showdown. The No. 15 BYU Cougars welcome the Arizona Wildcats to Provo, Utah, looking to defend their turf as a ranked home favorite. Both squads are riding high with pristine 1-0 records and one-game winning streaks, sitting deadlocked at 0-0 in conference play.

Arizona hits the road as a live underdog, fresh off receiving votes in the AP Top 25. They are hunting for an early-season statement win in hostile territory. Meanwhile, BYU wants to establish physical dominance and set a violent tone for its conference slate. The action kicks off on September 12, 2026, at 3:30 PM ET from LaVell Edwards Stadium.

My Arizona vs BYU predictions focus on ball security and who controls the pace. Below are the closing odds and final picks, including a rushing-prop angle.

Arizona vs BYU Predictions

• Score Prediction: BYU 27-Arizona 17 – BYU Wins, covers the spread, and the total goes Under.

I foresee a game script where BYU establishes the run early and never looks back. The Cougars will dominate time of possession, lean on their offensive line, and frustrate Arizona into making critical red-zone errors. Expect a grueling, physical battle that favors the more disciplined squad.

To forecast how this game unfolds, I have to look under the hood at the raw numbers. The stylistic differences between these programs are glaring. Arizona wants to push the tempo through the air, while BYU relies heavily on an imposing rushing attack to chew up the clock.

Arizona quarterback Noah Fifita orchestrates a dangerous passing game, logging 331 passing yards in their opener. However, the Wildcats have struggled mightily with ball security, coughing up three offensive turnovers already. That sloppy play is a concern against a BYU defensive scheme that feasts on mistakes. The Cougars have already snagged three interceptions.

BYU’s ground game produced 308 rushing yards in the 63-7 win over Utah Tech. The Cougars converted nine of 11 third downs, and Bear Bachmeier accounted for four touchdowns: three passing and one rushing. I expect that balance to keep BYU moving the chains against Arizona.

This trench warfare limits the effectiveness of Arizona’s aggressive front seven. The Wildcats have recorded 6.0 sacks, but BYU’s commitment to running the rock neutralizes obvious passing downs. If Arizona cannot force long third downs, their pass rush becomes a non-factor.

Arizona vs BYU Final Picks

My main game picks use the Polymarket contracts and BetMGM odds. The separate player prop below retains its Bet365 odds.

Against the Spread: BYU -7.5 — Yes at 48% on Polymarket

Backing the home favorite is my primary angle. The line has moved past the key number of seven, and BYU’s record gives me a stronger foundation than one big opening win: the Cougars are 24-4 since the start of 2024. Their defense also leads the FBS with 42 interceptions over that span. I’m backing BYU -7.5 to turn sustained drives and defensive takeaways into a two-score margin.

The Total: Under 48.5 (-108 at BetMGM)

The earlier sportsbook total fell from 53.5 to 48.5. BetMGM’s odds for the Over are set at 48.5 (-108), and I’m taking the Under. BYU’s offense is designed to bleed the clock, taking the air out of the ball while keeping Arizona’s explosive playmakers on the bench. With the Cougars draining the play clock on every drive, possessions will be extremely limited. Fading a shootout is the smartest play on the board.

Sportsbook Player Prop: LJ Martin Over 108.5 Rushing Yards (-115 at Bet365)

LJ Martin is the engine of this offense. Despite his yardage total inflating by 13 yards since opening, the over is still a strong play. BYU is converting third downs at a historic clip and running the ball relentlessly. Martin will see bell-cow volume, especially late in the fourth quarter when the Cougars are salting away a lead.

Arizona vs BYU Sportsbook Betting Splits

Looking at the college football public betting trends, the betting public is heavily invested in this matchup. BYU is commanding 69% of the spread money and 59% of the tickets. This unified support aligns perfectly with my expectation of a wire-to-wire victory for the home team.

The total, however, reveals a massive split between my read and the casual bettor’s perspective. An overwhelming 65% of the money and 56% of the tickets are hammering the Over. Since the line dropped significantly despite heavy public money banking on points, I am tracking a classic sharp advantage backing the Under.

On the moneyline, BYU is soaking up a staggering 98% of the handle. Barely anyone is brave enough to back an outright Arizona upset, further cementing the likelihood of a positive, run-heavy game script for the Cougars.
