College football's postseason frequently delivers thrilling moments, yet true upsets in the College Football Playoff (CFP) era have been less common, making those that do occur all the more memorable. This compilation examines a selection of the most significant upsets that have reshaped the narrative of the CFP, demonstrating that even the most favored teams are not immune to defeat.
Among the most astonishing outcomes was Miami's unexpected victory over Ohio State in 2025, a game where the Hurricanes' formidable defense, spearheaded by Rueben Bain Jr. and Keionte Scott, stifled the Buckeyes' offense. This win, against a team favored by 9.5 points, is considered the greatest upset in CFP history. Other notable surprises include TCU's dominant performance against Michigan in 2022, where the Horned Frogs, despite being considerable underdogs, scored 51 points. Similarly, Oregon's resounding win over Florida State in 2015 showcased Marcus Mariota's talent, dismantling a previously undefeated Seminoles squad.
The 2015 Sugar Bowl also saw Ohio State, battling injuries and starting a third-string quarterback, overcome powerhouse Alabama. Running back Ezekiel Elliott's exceptional performance fueled their path to an unlikely national title. Fast forward to 2021, and Ohio State once again defied expectations, defeating a highly-touted Clemson team led by Trevor Lawrence. Finally, Clemson's 2017 victory over Alabama, a team with a rich championship history, marked a pivotal moment for the Tigers, securing their first national championship in decades.
These compelling narratives from the College Football Playoff underscore the enduring spirit of competition and the possibility of extraordinary achievements against all odds. They remind us that dedication, strategic brilliance, and collective effort can lead to triumph, even when facing seemingly insurmountable challenges, inspiring fans and athletes alike with their tales of resilience and unexpected success.
