Texas Tech has the highest expectations. BYU is close behind.

Texas Tech enters 2026 with something it has never had to defend before: a Big 12 championship and a College Football Playoff appearance. Joey McGuire’s program is no longer selling possibility. It is trying to prove that last season changed the standard.

The Red Raiders begin with the highest expectations, and rightly so. They also begin with the league’s biggest quarterback question among the leading contenders. BYU has the established quarterback and veteran lines. Utah has a proven backfield but must replace both fronts. Houston has one of the conference’s most productive returning quarterbacks and a transfer-heavy line. The Big 12 race is not short on plausible answers; it is short on separation.

Texas Tech has the system—and a decision at quarterback

Mack Leftwich’s offense averaged 39.4 points and 461.4 yards per game in 2025. It was the Big 12’s only team with both 3,500 passing yards and 2,500 rushing yards. Cameron Dickey and J’Koby Williams each topped 800 rushing yards, giving the next quarterback a proven backfield and an offense that does not have to become one-dimensional.

The quarterback job remained open in the reviewed camp material. Will Hammond and Tulsa transfer Kirk Francis are the two candidates with meaningful college experience, and Hammond’s return from a 2025 knee injury makes his mobility and clearance important August questions. Left tackle Howard Sampson, center Sheridan Wilson and guard Jacob Ponton return, but two line jobs and the receiving order around tight end Terrance Carter Jr. still have to settle.

Texas Tech also has to replace premium defensive production. A.J. Holmes Jr. anchors the interior, and Wake Forest transfer Mateen Ibirogba is a major addition. Ben Roberts and Kansas State transfer Austin Romaine give the linebacker room an experienced pair. Brice Pollock is the established corner. The edge rotation and the rest of the secondary will decide whether the defense can resemble the championship unit rather than simply share its scheme.

BYU has the league’s sturdiest returning core

Bear Bachmeier led BYU to 12 wins as a true freshman and returns as the unquestioned starter. LJ Martin, the reigning Big 12 Offensive Player of the Year, gives the Cougars a physical offensive identity. All-American center Bruce Mitchell and several veteran linemen return around them.

That continuity is why BYU is close behind Texas Tech. It also makes the unresolved details more important. Martin missed spring after shoulder surgery. The Cougars must replace their top three pass catchers, and the leading receiver group—JoJo Phillips, Tei Nacua and Oregon transfer Kyler Kasper—has talent but less proven production. The backup quarterback job is unsettled, increasing the importance of keeping Bachmeier upright.

Kelly Poppinga takes over a defense with established leaders. Keanu Tanuvasa anchors the front. Cade Uluave joins Isaiah Glasker and Siale Esera at linebacker. All-American safety Faletau Satuala leads an experienced secondary. Poppinga does not need to start over; he needs to add pressure and disguise without damaging a unit that already communicates well.

Utah’s season will be decided by five new blockers

Devon Dampier and Wayshawn Parker give Utah a backfield that can carry a conference contender. Parker rushed for 981 yards at 6.58 yards per carry in 2025, while Dampier’s dual-threat ability shapes everything offensive coordinator Jason Beck can call.

The problem is impossible to hide: Utah must replace all five offensive-line starters, including two first-round tackles. The defensive line also replaces every starter. Johnathan Hall can steady the defense at linebacker, and the safety room is experienced, but Morgan Scalley’s first season as head coach will depend on whether two rebuilt fronts can become functional before Big 12 play.

Utah’s first three games are at home. That is the runway. The trip to Iowa State is the deadline.

Houston is the team most likely to crash the top group

Conner Weigman completed 65.2 percent of his passes for 2,705 yards and 25 touchdowns last season, then added 700 rushing yards and 11 scores. He is the clear starter and the center of Willie Fritz’s team.

Houston wants to reduce Weigman’s 171-carry workload without losing the threat that makes him difficult to defend. Oregon transfer Makhi Hughes, who previously produced consecutive 1,300-yard seasons under Fritz’s staff at Tulane, gives the Cougars a credible way to do it. Amare Thomas returns after 67 catches for 966 yards and 12 touchdowns, and Oregon State transfer Trent Walker adds another proven target.

The offensive line is a transfer-heavy rebuild with experienced pieces but no confirmed five-man combination. That room will decide whether Houston’s attractive skill-position setup travels through a schedule containing five Big 12 road games.

Oklahoma State can move faster than a normal rebuild

Eric Morris brought more than 80 newcomers to Oklahoma State, including 21 players who had played for him at North Texas. That is enormous turnover, but it also gives the Cowboys a ready-made offensive core.

Quarterback Drew Mestemaker threw for 4,379 yards and 34 touchdowns in 2025. Running back Caleb Hawkins rushed for 1,434 yards and 25 scores. Receiver Wyatt Young ranked seventh nationally in receiving yards. All three know the system. The question is whether a rebuilt offensive line and a far less settled defense can become Power Four-ready quickly enough to support them.

Five things that will decide the Big 12

1. Texas Tech’s quarterback choice

The defending champion has the system, backs and veteran anchors to remain on top. The conference race changes if Hammond or Francis cannot provide stable play early.

2. BYU’s new receiving order

Bachmeier and Martin establish the floor. Phillips, Nacua, Kasper and the tight ends will determine whether BYU can punish defenses that crowd the run.

3. The rebuilt fronts at Utah

Dampier, Parker and Hall are good enough to win games. Five new offensive-line starters and an entirely new defensive front create the widest range of outcomes among the leading teams.

4. Houston’s protection

Weigman, Hughes and Thomas form one of the conference’s best offensive trios. If the line settles, Houston can beat the teams ranked above it rather than simply make those games competitive.

5. The teams nobody can price cleanly in August

Oklahoma State’s imported offense, Iowa State’s yearly development and the experienced cores at Kansas State, TCU and West Virginia give the league its usual volatility. One clear quarterback answer can move a team several places in a hurry.

Texas Tech deserves to begin first because the Red Raiders own the trophy and return a proven system. BYU is close because its quarterback, running game and veteran lines reduce the number of things that must go right. Utah and Houston have strong cores with specific structural questions. That is the Big 12 in 2026: a champion worth respecting, a chase group with real answers and no lead large enough to feel safe.
