On Upset Watch: College Basketball Upsets Today

Nothing defines the magic of March quite like a staggering underdog victory, and the radar for college basketball upsets today is flashing brightly. We already saw the seeds of chaos planted during the First Four when No. 11 Miami (Ohio) stunned SMU with an 89-79 victory. The RedHawks knocked down an astonishing 16 three-pointers to secure their first NCAA Tournament win since 1999, proving that double-digit seeds are exceptionally dangerous when they catch fire.

Moving into Thursday's expansive slate, all eyes are on the notorious 12-5 and 13-4 matchups.

2026 NCAA Tournament Predictions: The Road to Indianapolis

As the hardwood action heats up, analysts and armchair experts are locking in their final 2026 NCAA tournament predictions. Oddsmakers currently list top seeds like Duke, Michigan, and Arizona as heavy favorites to eventually cut down the nets at Lucas Oil Stadium in Indianapolis on April 6. However, history constantly reminds us that regular-season dominance rarely guarantees a smooth path through the bracket.

Coaching experience plays a massive role in surviving the opening weekend. Purdue's Matt Painter boasts a remarkable 13-4 against-the-spread record in the Round of 64, making the Boilermakers a formidable force as they look to cruise past Queens NC. Similarly, Tom Izzo has Michigan State positioned for yet another patented March run, marking the Spartans' incredible 28th consecutive tournament appearance. Teams like these offer excellent value for those looking beyond the top overall seeds.

The ultimate survivor will need a blend of veteran leadership, reliable three-point shooting, and a little bit of luck to navigate the treacherous waters of the next three weeks. As Thursday's games transition into Friday's slate—bringing in fresh venues like Tampa, Philadelphia, San Diego, and St. Louis—the intensity will only multiply. Grab your remote, keep a red pen ready for those bracket corrections, and settle in for the unmatched thrill of the opening round.
