Entering last weekend, six Division I college basketball teams stood as undefeated. That number shrank to five after Michigan suffered an upset home loss to Wisconsin as a 19.5-point favorite. That result caused some shakeup in the second AP Top 25 college basketball poll of 2026, with Iowa State moving to No. 2 as a result.
With the loss to Wisconsin, Michigan dropped two spots to No. 4. The Wolverines also had an upset scare earlier in the week against Penn State, but escaped with a 74-72 win after the Nittany Lions missed a 3-pointer at the buzzer.

With Iowa State moving up one spot to No. 2 in the poll, it ties its highest ranking in program history. The Cyclones checked in at No. 2 in the poll last season, which was (at the time) the highest ranking in program history. Iowa State sits at 16-0 entering the week, with a critical showdown on the road against Kansas looming.
Speaking of the Jayhawks, Kansas dropped out of the poll after another loss in Big 12 play. Kansas fell to 1-2 against Big 12 competition after suffering an 86-75 loss to West Virginia. The Jayhawks earned their first conference win of the season earlier in the week after a dramatic comeback win against TCU.
