For some teams, the make-or-break game on the schedule is pretty clear — a nonconference matchup against a big-name program or a showdown with a hated rival.
But sometimes the season-defining game sneaks up on a team. Maybe it’s an unexpected loss that sends a team into a tailspin, or a last-second win that sparks a hot streak.
Either way, there always are certain games that fans circle on the calendar with a heightened sense of anticipation. (We suspect players and coaches do too, but good luck getting them to admit it.)
With that in mind, we asked our college football reporters to predict what the season-defining game will be for all 68 power-conference teams in 2026.
Oct. 17 at Miami. We cannot choose Alabama as the season-defining game because winning the opener against the Tide last year should have defined the season. Instead, the Seminoles went 5-7. The Miami game comes at a critical point in the schedule as Florida State opens ACC play against SMU on Labor Day, then plays Virginia and at Louisville before Miami. The rival Hurricanes just played for a national title. There is no better way to define a season than getting a win here. — Andrea Adelson
Sept. 5 vs. Ole Miss. The Cardinals open the 2026 season in Nashville against returning QB Trinidad Chambliss and Ole Miss. This game could set the table for Jeff Brohm’s team. If the Cardinals are able to beat the Rebels, who were semifinalists in last year’s College Football Playoff, they probably will feel confident looking at the rest of the schedule that there’s not a game they can’t win. — Lyles
Nov. 6 or 7 vs. Clemson. The Orange won at Clemson this past season, but that victory came at a painful cost as starting quarterback Steve Angeli tore his Achilles tendon and the Syracuse season fell off a cliff from there. Angeli is expected back for the start of 2026 and while Syracuse will have played eight games before Clemson, a win here would no doubt define the season — whether it is going poorly or well to that point. — Adelson
Oct. 3 at Florida State. Why not have Florida State as the season-defining game for the second year in a row? The Cavaliers’ double-overtime win over the Seminoles in 2025 helped launch them to a school-record 11 wins and an appearance in the ACC championship game. Winning in Tallahassee would essentially show Virginia is not going anywhere just yet. — Adelson
Oct. 24 vs. Kansas State. The Big 12 has two teams in our Way-Too-Early Top 25 — No. 7 Texas Tech and No. 11 BYU — and ASU will visit both of them in the back half of October. In between comes a visit from a retooled and potentially dangerous K-State team. A win would keep the Sun Devils’ Big 12 hopes ever so slightly afloat even if they lose one of the two big games, but a loss would doom them to also-ran status. — Bill Connelly
Sept. 12 at BYU. Brent Brennan’s Wildcats won their last five Big 12 games of 2025 to bounce back to 9-4 after a 4-8 stumble in 2024. Are Noah Fifita & Co. Big 12 contenders in 2026, or are they simply hoping for another solid season? Well, two weeks in, they’ll either be 0-1 in conference play, or they’ll have pulled an upset of a preseason top-15 team. That will be a solid partial answer right there. — Connelly
Oct. 17 vs. Notre Dame. If BYU wants to prove it belongs with the big boys, this is as close to a must-win game as it will play. It would have been an appetizing consolation bowl game last season after both teams narrowly missed the playoff, but here it could serve as a potential springboard to the playoff in 2026. — Bonagura
Oct. 24 vs. Texas Tech. It’s safe to say the Bearcats have this one circled on the calendar as former Cincinnati quarterback Brendan Sorsby makes his return to Nippert Stadium with the defending Big 12 champs. Texas Tech survived a 44-41 shootout on a missed game-tying field goal when these teams last met in 2024. For Cincinnati, this year’s game kicks off a challenging three-game stretch with Utah coming in next, followed by a road test at Houston. — Olson
Sept. 12 vs Missouri. It’s odd to put so much weight on a Week 2 matchup. But the Jayhawks are staring down a daunting slate in 2026 as they work to replace previous mainstays such as Jalon Daniels, Daniel Hishaw Jr. and Bryce Foster. If Kansas is going to improve on its 5-7 finish last fall, it’s going to have to get rolling with its new core early. What better time to start than with the program’s first visit from Border War rivals Missouri since 2005? — Lederman
Nov. 7 vs. BYU. First-year coach Morgan Scalley will try to emerge from Kyle Whittingham’s shadow throughout the 2026 season, but regardless of how the first eight games go, the tilt with BYU will likely shape how his debut campaign is remembered. It’s reasonable to think Utah could go into this game undefeated, but even if there are a few stumbles along the way, a win here would go a long way toward building momentum for the future. — Bonagura
Oct. 3 vs. Ohio State. The Hawkeyes haven’t faced Ohio State at Kinnick Stadium since 2017, when Nate Stanley threw five touchdowns as they stunned the Buckeyes 55-24. An early October win over Ohio State could propel Iowa into the Big Ten title and playoff conversations. — Trotter
Oct. 17 vs. Northwestern. The Spartans would obviously love to beat rival Michigan at the Big House on Nov. 7. But as new coach Pat Fitzgerald attempts to rebuild Michigan State, getting a win over his former school would be big for him — and for the Spartans’ chances of reaching bowl eligibility for the first time since 2021. — Trotter
Oct. 24 vs. Indiana. Ohio State is always the defining game for the Wolverines. But Michigan can prove it’s for real again against the defending national champs after two up-and-down seasons under Sherrone Moore. The Wolverines failed to defeat a ranked team last year and didn’t win one in 2024 until the stunning victory over the Buckeyes in the regular-season finale. — Trotter
Oct. 24 vs. Iowa. The Gophers got embarrassed last season in Iowa City 41-3, and the Hawkeyes have won 10 of the last 11 meetings in the rivalry. To get back the Floyd of Rosedale trophy, the Gophers will have to finally figure out how they can generate offense against Iowa. Minnesota has failed to score more than 14 points over the last four meetings in the series. — Trotter
Sept. 19 at UCLA. A Week 3 game is not usually season-defining, but Purdue must establish early on that coach Barry Odom’s second season will be different, especially in Big Ten play. The Boilermakers went 0-9 in league games last fall while being outscored 309-130. UCLA is in transition under new coach Bob Chesney, and a Purdue win in Pasadena — the team’s first game there since the 2001 Rose Bowl behind quarterback Drew Brees — could be the catalyst Odom needs. — Rittenberg
Nov. 28 vs. USC. The Bruins seemingly have a long way to go before they’ll be viewed as competitively relevant in the Big Ten, but in this era that can happen overnight. That’s why the range of what’s possible in Bob Chesney’s first year as coach is so broad. There isn’t really one game on their schedule that outweighs the rest until the rivalry game in the finale. — Bonagura
Sept. 26 vs. Oregon. It could easily change by the end of the year, but USC’s trajectory for 2026 will be set by how it fares against the Ducks in the fourth game of the season. A loss to the Ducks will keep USC outside the national conversation just as conference play begins, while a win would signify a meaningful step toward returning to national relevance. — Bonagura
Nov. 21 vs. Indiana. The Huskies should enter 2026 with high expectations and have a relatively manageable schedule over the first two months. However, with Indiana and Oregon to end the year, a strong start to the season could easily get wiped away. A win against the Hoosiers, though, would be the program’s biggest win in years. — Bonagura
Sept. 19 vs. Georgia. I want to be clear that I don’t think the result of a game for a first-year head coach against one of the standard-bearers of the SEC is necessarily going to define Arkansas’ season. That feels extreme, so I’m cheating a bit here. I do think this game could have a lot of sway in building momentum for a program that needs to feel something. If Ryan Silverfield has his team competing against the Bulldogs this early, it could be a potentially massive building block. — Lyles
Sept. 19 vs. Florida. The Tigers have suffered through five straight losing seasons, and now they’ve turned to former South Florida coach Alex Golesh to get things back on track. Golesh’s hiring received mixed reviews on the Plains, and he could certainly earn some respect with a victory over the Gators in the SEC opener. He guided the Bulls to an 18-16 upset of the Gators on the road last season. — Schlabach
Oct. 31 vs. Georgia. A good starting point for new coach Jon Sumrall is to beat rival Georgia, something predecessor Billy Napier never did. Florida has lost eight of its last nine games to the Bulldogs, its worst stretch since the 1970s. Given the shifting SEC schedules, Georgia is the only annual SEC rival remaining on the schedule. Florida must find a way to win. — Adelson
Oct. 10 at Alabama. The Bulldogs exorcised some of their Crimson Tide demons by routing Alabama 28-7 in last season’s SEC championship game. It was Georgia’s second victory in eight tries against Alabama under coach Kirby Smart. The Bulldogs’ last victory in Tuscaloosa, Alabama, came in 2007, when current NFL MVP Matthew Stafford threw a 25-yard touchdown in overtime in a 26-23 win. — Schlabach
Nov. 14 vs. Texas. It would have been easy to pick the Ole Miss matchup, but it is hard to pick games in September as season-defining. Alabama or Tennessee would fit the bill here, too. But given where this game falls in the schedule — and the preseason CFP expectations for both teams — this could be the one that ultimately defines the season for the Tigers. — Adelson
Sept. 26 vs. Missouri. Jeff Lebby will be working with another drastically remodeled roster in 2026 and could desperately use some early traction. After road trips to Minnesota and South Carolina, this game could produce a win, a 3-1 record and happy headlines. Or it could produce a loss, a 1-3 record and a very hot seat for the head coach. — Connelly
