Big Ten spring football preview: Key storylines, positions and players to watch

Spring camps are open across the Big Ten, and with national signing day in the rear-view mirror and spring games on the horizon, every program is searching for clarity before the 2026 season kicks off. Reigning national champion Indiana begins life after a storybook run, while traditional powers such as Michigan, Iowa and Michigan State recalibrate under either new coaches or new expectations. Here is a team-by-team look at the most compelling storyline, a position that bears watching, and the single player who could shape each squad’s offseason narrative.

Illinois enters spring off the best two-year stretch (19 wins) in school history, yet coach Bret Bielema knows sustaining success in Champaign has proved elusive. The Illini must replace quarterback Luke Altmyer and star pass rusher Gabe Jacas, and new defensive coordinator Bobby Hauck will install a scheme the roster has never run. The offensive focus is reviving a ground game that finished 89th nationally. Keep an eye on the offensive tackle spots, where first-team All-Big Ten left tackle J.C. Davis and Senior Bowl invitee Melvin Priestly must be replaced. Transfer Christian Martin (Colorado State) and juco additions TJ Taylor and Maika Matelau will compete with holdover Nathan Knapik. Quarterback Katin Houser, who threw for 5,306 yards and 37 touchdowns in 19 starts at East Carolina, is the player to watch as he tries to replicate Altmyer’s transfer success.

Indiana’s first title defense under Curt Cignetti will be staged with a largely new cast. Gone are quarterback Fernando Mendoza, both 1,000-yard rushers, the top two wide receivers and several defensive standouts. Cignetti aggressively mined the portal, but the receiving corps still needs sorting. Charlie Becker flashed in the playoff and will pair with Michigan State transfer Nick Marsh, yet Elijah Sarratt and Omar Cooper Jr. take 28 combined touchdowns with them. Running back Khobie Martin averaged 6.5 yards per carry and scored on 7.7 percent of his attempts; he is the breakout candidate to ease new quarterback Josh Hoover’s transition.

Iowa believes its defense-first formula can carry it from playoff near-miss to actual contention. The Hawkeyes return safety Zach Lutmer (three interceptions, seven pass breakups) to anchor a secondary that must replace Xavier Nwankpa and Koen Entringer. Offensively, coordinator Tim Lester is staging a true quarterback battle between Wake Forest transfer Jeremy Hecklinski and Auburn-tested Hank Brown while trying to prop up a passing attack that ranked 127th. Sophomore tight end DJ Vonnahme (29 catches, 434 yards) is the most proven weapon.

Maryland is desperate to end an eight-game slide that sunk the 2025 season. New offensive coordinator Clint Trickett will build his attack around freshman record-setter Malik Washington (2,963 yards), but the bigger fix is up front: the Terps allowed 175.6 rushing yards per game. Transfers Armon Parker (Washington), Lavon Johnson (Texas) and Derrick LeBlanc (UCF) will be counted on immediately. Spring also marks the debut of five-star defensive end Zion Elee, the highest-rated signee in program history, who joins last year’s productive freshmen Sidney Stewart and Zahir Mathis to form a potentially elite young pass-rush trio.

Michigan’s transition to Kyle Whittingham begins with establishing a physical identity on both lines. The Wolverines must replace edge rusher Derrick Moore and linebacker Jaishawn Barham, who combined for 14 sacks, while sophomore quarterback Bryce Underwood tries to cut down seven interceptions over his final five games of 2025. Underwood’s chemistry with coordinator Jason Beck, who revitalized Utah’s offense, will determine whether Michigan can rejoin the league’s elite.

Michigan State welcomes Pat Fitzgerald back to the sideline and needs immediate offensive-line improvement after allowing the 123rd-most sacks and finishing 110th in rushing offense. The Spartans return tackle Conner Moore and add transfers Ben Murawski (UConn), Nick Sharpe (South Carolina) and FCS All-American center Trent Fraley. Cornerback Charles Brantley, who rejoined the program after a brief Miami stint, led MSU with three picks in 2024 and teams with Tre Bell (Iowa State) to remake the secondary.

Minnesota has won five straight bowl games yet cracked double-digit victories only once under P.J. Fleck. Defensive end Anthony Smith, who recorded 12.5 sacks last fall and is closing in on the school’s career record, spearheads a defense that must offset the departure of star safety Koi Perich (Oregon). The Gophers hope an experienced defense plus a maturing offense equals a breakthrough year.

Across the conference, UCLA will operate under new coach Bob Chesney after his College Football Playoff run at James Madison, and Nebraska, Northwestern, Ohio State, Oregon, Penn State, Purdue, Rutgers, USC and Wisconsin all stage their own personnel chess matches before the 2026 campaign begins.
