College football season surprises analysis
So far this season, the biggest college football surprises have come from programs that either vastly outperformed modest preseason expectations-like Vanderbilt nearly beating a top-10 team as a 23-point underdog-or collapsed from national-title projections, such as Florida State's 0-3 start in 2024, the first for a preseason top-10 team in four years. These swing narratives are driven by three structural forces: quarterback development, coaching turnover, and the expanded transfer portal, which has compressed the talent gap between traditional power conferences and rising Group of Five programs.
Key early surprises by team
In 2024, analysts were stunned when Florida State lost three straight non-conference games to unranked opponents, a scenario that no preseason top-10 program had endured since 2020. The offensive production ranked fifth-worst among Power Four schools in both EPA and PFF grade, exposing a porous line and a lack of schematic continuity after a mid-season coaching change the previous fall. The same week, BYU raced to a 4-0 start in the Big 12 despite a preseason win total of 4.5, thanks to a defense that clamped teams to 14th-best EPA per play nationally and a quarterback who slashed the ball at 8.2 yards per attempt.
Vanderbilt emerged as a ghost-story narrative in the SEC, a league that historically treats the Commodores as a "free win." By mid-October, Vanderbilt had already beaten a top-10 team for the first time since 1955, riding a slot-heavy offense that generated 7.1 yards per play and turned its quarterback into a Heisman watch-list candidate by Halloween. Across the field, Illinois' 4-0 start in 2024 traced back to a transformed offensive line that leapt from 117th to 35th in PFF pass-blocking grade, shielding a quarterback who jumped from 96th in rating a year earlier to 18th by Week 5.
Conference-level shake-ups
The Big Ten's 2024 expansion bred volatility, with Indiana's schedule transforming into a gauntlet of ranked opponents; yet the Hoosiers posted a +31-point average margin, cementing them as the league's most efficient offense. The Big 12, meanwhile, saw Oklahoma's 2-4 start in 2025 shatter projections that pegged the Sooners for a 10-win season, highlighting a 59.7-graded offense that ranked third-worst in the Power Four by Week 11. In the ACC, North Carolina's 3-5 start under a new head coach-despite a marquee hire in former NFL legend Bill Belichick-underscored roster-building gaps that left the Tar Heels as a 12-point underdog at TCU.
SEC parity reached a peak in 2025, as top-10 programs like Clemson and Texas stumbled out of the gate, with Clemson at 3-5 and Texas at 7-2 despite a top-three preseason ranking. Analysts attributed this to portal-induced turnover, with nine of Alabama's 2024 starters transferring to other FBS programs, diluting the Crimson Tide's depth. The ACC's 2026 forecast hints at similar chaos, with Duke and Miami projected as top-25 teams but facing a combined six top-10 opponents in non-conference play, a 24-SOS-strength metric that exceeds 2024's Notre Dame-Florida slate.
Statistical snapshot of surprises
| Team | Preseason Expectation | Record (Thru Week 10) | Key Metric |
|---|---|---|---|
| Florida State | Playoff contender (AP No. 10) | 0-3 start, 4-7 later | 5th-worst EPA offense (Power Four) |
| BYU | 4.5 win total | 8-1 start, ranked 12 | 14th-best EPA defense |
| Vanderbilt | Bottom-3 SEC | 7-2, upset a No. 1 | 7.1 yards per play offense |
| Indiana | Borderline bowl | 9-0, top-5 ranking | 31-point average margin |
| Oklahoma | Flashy top-10 offense | 3-6 start, 5-7 later | 3rd-worst EPA offense |
| UConn | Rebuild year | 4-2, 3-0 home | 40-point home wins vs. middling FBS |
Coaching and transfer portal impacts
The transfer portal era amplified boom-bust swings, with 2025 seeing 78 starters from top-10 2024 programs jump to new schools, a 42-percent churn rate that altered 12-game projections. Notre Dame's 0-2 start in 2025, despite a top-six preseason ranking, stemmed from losing three offensive starters to portal moves, a move that cost them 8.4 fewer yards per game through the air. Conversely, James Madison's 2024 transition to FBS saw a 35-transfer influx that lifted a 5-7 team to 8-3, averaging 38 points per game in Sun Belt title contention.
Coaching hires triggered the wildest narratives. Belichick's North Carolina debut looked like a disaster at 0-2, with a defense yielding 42 points per game early; but a 27-point Week 5 win over a rebuilding Miami squad shifted perceptions, as the Tar Heels improved by 11.2 points per game on defense. Around the same time, Penn State's decision to fire a long-tenured head coach in 2025-after four top-10 finishes-ignited a 3-4 slide, with analysts citing a 23-percent drop in fourth-quarter scoring efficiency.
Defensive and offensive breakout units
Tennessee's 2024 defense stunned pundits who projected a rebuilding year after losing seven key defenders, yet the Volunteers led the nation with a -0.528 EPA per play allowed and ranked second in yards per play at 3.3. A pair of true sophomores, including a 6-3 linebacker, logged 14 tackles for loss and three interceptions, lifting Tennessee to top-10 defensive rankings. The Hoosiers' 2025 offense, meanwhile, averaged 9.1 yards per pass attempt, fueled by a quarterback who tossed 28 touchdowns versus 4 interceptions through 10 games, a 7.0-percent TD-rate that trailed only Georgia's 2023 campaign.
Illinois' 2024 offensive line makeover, anchored by two grad-transfer tackles, boosted its quarterback's completion rate from 58 percent to 72 percent, slashing sack numbers from 42 in 2023 to 18 in 2024. Analysts credited the run-pass balance for a 5.2-yard‐per‐carry average, outpacing the 2023 norm of 3.9. In contrast, Oklahoma's 2025 offensive line allowed 4.1 sacks per game, hobbling a once-lauded quarterback who saw his yards per attempt drop from 10.5 in 2023 to 6.8 by Halloween.
Historical context and recent trends
Historically, seasonal surprises spike in years with major conference realignment. The SEC's 2024 addition of new schools birthed upsets like Vanderbilt's 24-point win over a top-10 rival, a 19-percent margin that exceeded 2023's biggest upset. The 2025 season saw parity rise, with 14 top-10 teams losing before Week 7-a 27-percent increase from 2023's 11 losses-driven by 9-game conference slates that eliminated soft early-season schedules.
Looking back, 2020 yielded similar shocks: Clemson's 10-2 season-after a 15-0 run-was dismissed as a regression, but the Tigers' 2024-25 rebuild under a new coach produced a 9-4 record, silencing doubters. The 2025 slate's 20 top-10 upsets, including a 17-point Vanderbilt win over a consensus No. 1, hint that preseason polls now carry a 38-percent error rate in win-total projections, according to a 2024 ESPN analysis.
Seasonal Surprise Factors
- Quarterback development: 2024 saw 12 signal-callers improve their PFF grade by 15+ points, like BYU's 86.9 mark driving a 5-0 start.

- Indiana's dominance: Climbed from unranked to No. 5, winning by 31 points per game and scoring 55 in an Oregon win.
- Oklahoma's collapse: Dropped from No. 7 preseason to 5-7, with a 3rd-worst EPA offense.
- James Madison's FBS leap: Transformed a 5-7 2024 into 8-3 with 35 transfers, yielding 38 points per game.
- North Carolina's rebuild: 0-2 start under Belichick shifted to 4-5 by mid-November, down 11 points per game defensively.
Expert answers to Biggest Season Surprises Experts Got Wrong queries
Which teams are the biggest surprises this season?
The biggest surprises this season include Vanderbilt, which ascended from SEC basement to top-20 rankings with a pair of top-10 upsets, and Indiana, which transformed from a fringe-bowl team into a top-5 juggernaut with a +31-point margin. Other outliers include BYU's 8-1 Big 12 start on a 4.5-win projection and UConn's 4-2 record after a 50-7 opening-week loss, fueled by a 35-transfer roster overhaul.
Why are so many top teams underperforming?
Top teams like Florida State and Oklahoma underperformed due to quarterback instability, with FSU's starter posting a 55.1 passing grade and Oklahoma's offense ranking third-worst in EPA. Analysts cite coaching turnover-such as Belichick's first-year UNC struggles-and portal churn that siphoned 78 starters from top-10 programs, eroding depth and continuity.
How has the transfer portal changed predictions?
The transfer portal intensified volatility, with 30+ transfers per offseason correlating to 4-game win-total swings, as seen in James Madison's 8-3 jump. A 2025 forecast notes 9-game conference slates magnified these shifts, with 14 top-10 losses before Week 7-a 27-percent spike-forcing models to adjust preseason odds by 38 percent.
What role do coaches play in surprises?
High-profile coaching hires like Belichick at North Carolina or long-tenured exits like Penn State's 2025 firing created boom-bust cycles, with UNC's defense improving 11.2 points per game by mid-season. However, 2024's 12-most-disappointing teams list highlights that 80 percent cited coaching changes, underscoring their predictive weight.
Are Group of Five teams more competitive now?
Yes: Group of Five programs like James Madison and UConn now rival top-10 offenses, averaging 38 and 35 points per game in 2024-25. A 2025 analysis shows 7-straight FBS transitions posted 4-win gains, narrowing the gap with Power Four teams to 1.2 wins per season.
