Week 9 in Review: Big Games and Upsets

Iowa State's Escape Over Oklahoma State Reshapes the Big 12

Iowa State's 51-49 win over Oklahoma State on Saturday carried the highest excitement index of the week at 8.99, and for good reason. Oklahoma State entered with a 60 percent pregame win probability, meaning the Cyclones pulled off a two-point upset in a game that came down to the final moments. In a Big 12 that has spent the season redistributing power, this result matters more than the margin suggests.

The Cyclones' ability to hold off a late Oklahoma State push in a one-score finish signals something worth tracking in conference standings. Two-point games are often decided by circumstance, but Iowa State's survival — against a program that came in favored — opens different scenarios for how the remainder of the season sorts itself. That tight margin matters less than the fact that Iowa State now sits in a position to control its own path in ways it might not have a week ago.

The Upset Cascade: Pregame Favorites Turned on Their Head

Eight teams won despite pregame models favoring their opponents. The most significant was South Carolina's 42-25 demolition of Oklahoma, where the Gamecocks entered with just a 40 percent win probability. That 17-point margin is the week's widest upset by result.

Ohio State's loss to USC (30-18, pregame 25% chance) ranks as the most shocking upset by pregame modeling — a 12-point swing for a program that came to the Pacific Coast as a heavy favorite. Similarly, Clemson's 36-24 win over Florida State, where Clemson was given 33 percent odds, represented a 12-point defeat for a conference rival many believed would compete for Atlantic positioning.

The other upsets — Washington over Nebraska (14% pregame), SMU over Syracuse (17%), Kansas State over Colorado (32%), Marshall over Old Dominion (34%), and Troy's stunning 24-21 win at James Madison (4% pregame) — paint a picture of a week where favored teams simply failed to execute in critical moments.

Troy's result stands out as the most improbable. Coming in with a 4 percent win probability at James Madison, the Trojans' three-point victory represents the kind of outcome that tests models severely. Those are the games that happen once per season across FBS, and Week 9 produced one.

One-Score Finishes Define the Week

Seven games were decided by three points or fewer. Beyond the Oklahoma State-Iowa State barnburner, Texas State nearly took down Boise State (45-46 finish), Illinois held off Maryland at 20-17, and Miami survived North Carolina 38-35 despite entering as a heavy favorite (92% pregame).

These tight results reflect either exceptional coaching or exceptional uncertainty — or both. The sheer volume of one-score finishes across 56 games suggests that separation between tiers has compressed. Tulane's eight-point escape over Charlotte (38-31) and Florida Atlantic's seven-point loss to North Texas (41-48) round out the high-excitement category, indicating that mid-tier programs are playing much closer to their ceiling than historical patterns would predict.

The reset continues. Iowa State's survival and the cascade of upsets leave the back half of the season with significantly more viable paths than pregame models suggested.
