The Sweet 16 field is taking shape as 16 teams battle Sunday for the final eight spots in the second weekend of the 2026 men's NCAA tournament. ESPN analysts Jeff Borzello and Myron Medcalf break down the critical matchups, starting with Purdue facing Miami in a clash of contrasting styles. The Boilermakers' size advantage and Braden Smith's playmaking could prove decisive.

In the afternoon slate, Iowa State takes on Kentucky despite Joshua Jefferson's likely absence. The Cyclones' perimeter defense and Milan Momcilovic's shooting could neutralize Kentucky's backcourt, though the Wildcats must protect the ball against Iowa State's aggressive pressure. Kansas faces St. John's in a battle of elite big men, with Flory Bidunga's performance potentially determining the Jayhawks' fate.

The evening session features Virginia against Tennessee, where the Cavaliers' 3-point shooting meets the Vols' offensive rebounding prowess. Nate Ament's impact could be the difference for Tennessee, while Virginia needs Thijs De Ridder to maintain their outside touch. Florida closes the day against Iowa, with the Gators' athleticism and defensive pressure testing the Hawkeyes' system built around point guard Bennett Stirtz. The Sweet 16 picture will be complete by Sunday night, setting up next weekend's regional semifinals.
