Latest 2025 NCAA Basketball Shockers: Power Rankings & Upsets Reshaping March Madness

College hoops fans are in for a December blockbuster as today’s 60-plus-game slate features ranked clashes, rivalry grudge matches and a neutral-site No. 1 vs. SEC shoot-out that could reorder the AP Top 25. Top-10 spotlight • No. 1 Arizona puts its perfect record on the line against No. 12 Alabama in Birmingham (9:30 p.m. ET, ESPN). The Wildcats have stormed to 8-0 behind a 95-0 mark when leading by 20+ since 2019, while the Crimson Tide already own seven 90-point wins this season. A Tide upset would almost certainly restore the SEC’s presence in the top five next Monday. • No. 4 Iowa State, fresh off a 23-point takedown of then-No. 1 Purdue, hosts rival Iowa (8 p.m., FS1). The Cyclones are chasing their fourth straight victory over an AP No. 1 or conference rival in less than 12 months as senior guard Tamin Lipsey eyes another statement game. • No. 7 Houston meets Jackson State (8 p.m., ESPN+) as Kelvin Sampson pursues win No. 808 and a 30th straight triumph over unranked foes, the longest active streak in D-I. Marquee non-conference showdowns • Marquette vs. No. 6 Purdue (2 p.m., Peacock): Zach Edey’s successor Noah Clingan looks to steady the Boilermakers after their first loss, but Shaka Smart’s Golden Eagles ride a top-10 offense that forces turnovers on 21 % of possessions. • Indiana at Kentucky (7:30 p.m., ESPN): The Hoosiers, unranked but dangerous, try to sink a Wildcats squad that just fell out of the poll for the first time in two seasons. • Texas Tech vs. No. 17 Arkansas in Dallas (noon, ESPN2): Two top-20 defenses collide as Razorbacks freshman guard Trevon Brazile looks to extend coach John Calipari’s 12-1 mark vs. unranked opponents while ranked. Upset watch St. John’s welcomes Iona at MSG (noon, TNT) with Rick Pitino chasing his 12th straight home win; Providence-Butler (2 p.m., TNT) and Rutgers-Seton Hall (8 p.m., FS1) add Big East intrigue.

Players to track • Arizona sophomore wing Brayden Burries, averaging 22.4 PPG on 44 % from deep, faces the nation’s fastest offense in Alabama. • Virginia freshman sniper Jacari White looks to extend his school-record 12 straight made threes tomorrow vs. UMES. • BYU’s AJ Dybantsa goes for a ninth consecutive 15-point game Tuesday against Clemson at Madison Square Garden.
