Ohio State starts on top. Oregon and Indiana won’t make it easy.

Ohio State owns the preseason lead. Oregon brings back a playoff quarterback and one of the league’s most imposing defensive fronts. Indiana has the trophy, the same coordinators and a roster built to make a major transition at quarterback less painful. The conference’s unofficial media order places them first, second and third, but the football beneath that order is far more interesting than the ballot.

Ohio State has the best offensive starting point

Julian Sayin and Jeremiah Smith give Ryan Day the conference’s cleanest quarterback-receiver foundation. Sayin completed 77 percent of his passes for 3,610 yards and 32 touchdowns in 2025. Smith caught 87 passes for 1,243 yards and 12 scores. Bo Jackson returns after a 1,000-yard freshman season, and four offensive-line starters are back.

Arthur Smith’s arrival as offensive coordinator should add more weight to the running game, but Ohio State’s ceiling will still be defined by protection. The Buckeyes allowed five sacks in each of their final two losses last season. The exact five-man line and the supporting roles at receiver and tight end still have to settle.

The defense faces a different challenge. Arvell Reese, Sonny Styles, Caleb Downs and Davison Igbinosun are gone. Jermaine Mathews Jr. and Jaylen McClain bring starting experience to the secondary, while James Smith, Eddrick Houston and a deep transfer group must replace production up front. Ohio State has plenty of talent. What it does not have is the same established defensive voice at every level.

Oregon has the strongest answer to Ohio State

Dante Moore threw for 3,565 yards and 30 touchdowns in 2025 and returns to lead an offense that does not need to reinvent itself. Jordon Davison and Dierre Hill Jr. combined for 1,323 rushing yards and 15 touchdowns as freshmen. Nebraska transfer Dylan Raiola gives the quarterback room unusual experience behind Moore.

The concern is the offensive line. Oregon had not settled its top five in spring, and its semifinal loss to Indiana showed how quickly the offense can narrow when the backfield is depleted and the line loses control. Davison’s health, the line’s cohesion and the division of duties under new offensive coordinator Drew Mehringer are the three details that matter most early.

Defensively, the Ducks can build around A’Mauri Washington, Matayo Uiagalelei, Bear Alexander and Teitum Tuioti. Minnesota transfer Koi Perich is the most prominent candidate to replace Dillon Thieneman at safety. That gives Dan Lanning a championship-caliber front and a gifted replacement on the back end, even as the second wave and communication roles come into focus.

Indiana’s title defense is a test of structure

Curt Cignetti does not have Fernando Mendoza, but he does have the same coordinators and a veteran spine through the middle of the roster. TCU transfer Josh Hoover threw for 3,472 yards and 29 touchdowns in 2025. He inherits an offensive line led by Carter Smith, Drew Evans and Bray Lynch, with Wisconsin transfer Joe Brunner adding another experienced option.

The transition is everywhere else. Indiana must rebuild its receiver and running-back rotations, replace three established edge players and settle several jobs in the secondary. Charlie Becker, Nick Marsh and Shazz Preston headline the receiver competition. Tyrique Tucker returns after producing 12 tackles for loss and six sacks, while Isaiah Jones becomes a central communicator at linebacker.

The early schedule gives Hoover and the new skill group four consecutive home games. Then the test changes quickly: Ohio State and Michigan arrive in back-to-back weeks later in the season. Indiana’s title defense will not be about recreating 2025 player for player. It will be about whether Cignetti’s structure can make another group cohere before the margin disappears.

The chase group has four very different cases

USC brings back Jayden Maiava, both leading rushers and all five offensive-line starters. That is enough continuity to make Lincoln Riley’s offense dangerous from the first week. The questions are at receiver and on defense, where Gary Patterson is installing a more multiple 4-2-5 and sorting through secondary health and linebacker roles.

Michigan’s season revolves around Bryce Underwood’s development and Kyle Whittingham’s first year in Ann Arbor. Jordan Marshall gives the Wolverines a proven running-game anchor, and the defensive front should remain deep. The passing game and thinner position rooms will determine whether Michigan can stay with the top group.

Penn State is attempting the league’s boldest rebuild. Matt Campbell imported quarterback Rocco Becht, offensive coordinator Taylor Mouser and a large Iowa State contingent. Familiarity should help, but Becht’s health, a largely new offensive line and the search for a lead receiver make the first season difficult to price.

Washington and Iowa are the next two teams capable of complicating the order. Washington has proven receiving production and a defense with several defined pieces under Ryan Walters, but both lines are developing. Iowa has coaching continuity and experienced skill players, yet the quarterback decision and the replacement of seven of its top eight defensive linemen will shape its ceiling.

Seven players and rooms that can swing the race

Julian Sayin and Ohio State’s protection

Sayin has already proved he can produce. The question is whether the line can give him clean answers when the schedule reaches Texas, Oregon and Michigan.

Jeremiah Smith, Ohio State

No player in the league changes coverage plans more immediately. If the secondary receiving options become dependable, opponents cannot devote the entire game plan to Smith.

Dante Moore, Oregon

Moore’s experience gives Oregon a high floor. His ability to carry the offense when the line or backfield is stressed will decide whether the Ducks can win the biggest games.

Oregon’s defensive front

Washington, Uiagalelei, Alexander and Tuioti can control games without constant pressure help. If the depth behind them holds, Oregon can survive the closing stretch.

Josh Hoover, Indiana

Hoover does not need to be Mendoza. He needs to distribute the ball, protect the offense from negative plays and let Indiana’s veteran line and defense set the terms.

USC’s receivers

Maiava and the line are established. Tanook Hines’ recovery, Terrell Anderson’s arrival and the development of a young group will determine how explosive the Trojans can be.

Bryce Underwood, Michigan

Michigan can run the ball and defend. A meaningful leap from Underwood would give the Wolverines the element most likely to change their place in the conference.

Ohio State begins with the most complete offensive case. Oregon has the quarterback and defensive front to beat anyone. Indiana has the strongest recent proof and a staff that has already shown it can integrate change. The Big Ten has spent three seasons refusing to belong to one program. There is no reason to expect 2026 to become orderly now.
