Iowa Stuns Michigan 20-19 on 91-Yard Final Drive as Wolverines Rue 8 Penalties

Q: After a chaotic Week 4 of upsets, which fallen powerhouse will plummet furthest in the AP Top 25 rankings?

Ole Miss looks most likely to fall the furthest. The Rebels entered the day at No. 4 and were not just upset, but overwhelmed by Florida 52-28. That margin matters. Poll voters typically punish top-five teams more sharply when the loss is lopsided and comes against a lower-ranked or unranked opponent, and Florida controlled the game with 302 rushing yards plus strong field position from London Montgomery’s returns. Michigan should drop, but probably not as far. The Wolverines were No. 18 and lost 20-19 at home to No. 17 Iowa on a last-second touchdown. That is a damaging loss because it came at home, yet it was also a narrow defeat to another ranked team. Teams in that range often slide several spots rather than collapse. Tennessee also lost, but its profile is more protected. The Vols fell 20-17 to No. 1 Texas, and they nearly stole it late. Losing close to the top-ranked team usually does not trigger a major plunge from the mid-teens. If Texas A&M, Oregon or Missouri also lost in the later ranked matchups, they would be candidates for notable drops depending on margin and opponent. But based on the completed headline upsets in the afternoon window, Ole Miss has the clearest case to tumble the most because it suffered the worst combination a voter reacts to: elite ranking, bad loss, and decisive scoreline.
