The Sweet 16's opening night was an exercise in bracket chaos. Only one of four favorites covered the spread, and two lost outright. Iowa authored the most dramatic finish, erasing a double-digit first-half deficit against Nebraska and ripping off back-to-back threes in the final three minutes to win 77-71 as 1.5-point underdogs. Illinois authored the defensive performance of the tournament, suffocating Houston's offense in a 65-55 win that produced just 120 combined points — 21.5 under the total. The under was a lock almost from tipoff, with over probability never climbing above 50%.
Texas gave Purdue everything it could handle in the night's most dramatic game. The Longhorns led 70-66 with under five minutes to play, and Purdue's cover probability against the 8.5-point spread sat in single digits for the final seven minutes. Trey Kaufman-Renn's buzzer-beating tip-in gave the Boilermakers a 79-77 win, but the 2-point margin was a far cry from what spread bettors needed. Arizona was the lone favorite to take care of business, steamrolling Arkansas 109-88 in a 197-point offensive explosion — the highest-scoring game of the tournament and 30.5 points over the total.
Purdue 79, Texas 77 — The most dramatic finish of the day, and a nightmare for Purdue spread backers. The Boilermakers led 39-35 at halftime and stretched the advantage early in the second half, but Texas stormed back. Tramon Mark's three-pointer tied it at 58-58 with 10 minutes left, and the Longhorns took a 70-66 lead on a Tramon Mark three with 5:20 remaining. Purdue's cover probability plummeted to single digits and stayed there the rest of the way. The Boilermakers clawed back — Oscar Cluff's putback, Fletcher Loyer's three, and Braden Smith's free throws kept them alive — but it took Trey Kaufman-Renn's tip-in at the buzzer just to win by 2. The 8.5-point spread was never in play after halftime. The over cashed easily at 156 against a 146.5 line, locked in by the midway point of the second half.
Iowa 77, Nebraska 71 — Iowa pulled off the upset of the night, but this one looked nothing like an upset for the first 25 minutes. Nebraska raced out to a 40-28 lead late in the first half behind Sam Hoiberg and Pryce Sandfort, with cover probability peaking at 76.5%. The over was essentially decided by then — over probability hit 95% before halftime in a game with a 131.5 total that would finish at 148. Iowa chipped away after the break, with Bennett Stirtz and Cooper Koch combining for a barrage of threes to erase the deficit. Stirtz's 28-foot bomb with 2:10 left put Iowa ahead 68-65, and Tate Sage's dagger three from 24 feet made it 71-65 to seal the upset. Nebraska's frantic final-minute rally — including Braden Frager's offensive-rebound three — fell short. A complete second-half collapse for the Cornhuskers.
Illinois 65, Houston 55 — A defensive masterclass from Illinois that strangled Houston's offense from start to finish. The first half was a rock fight — Illinois led 24-19 at the break, and the combined 43 points through 20 minutes made the 141.5 total look absurd. Over probability never climbed above 50% in this game. Illinois pulled away in the second half with a devastating run, pushing the lead to 38-26 on Jake Davis and David Mirkovic buckets before extending to 44-26 on a Ben Humrichous three. Houston never got closer than 10 the rest of the way. The Cougars managed just 55 points — their lowest output of the season — and the final total of 120 came in 21.5 points under the line. Houston was a 2.5-point favorite, but the model's cover probability for the Cougars never exceeded 53.6%, signaling this was always going to be Illinois's game to control.
Arizona 109, Arkansas 88 — Arizona put on an offensive clinic in a 197-point shootout — 30.5 points over the 166.5 total. The Wildcats raced to a 28-17 lead through 10 minutes and led 54-43 at halftime, with both teams trading baskets at a furious pace. Arizona's lead ballooned to 78-57 midway through the second half as Brayden Burries, Koa Peat, and Jaden Bradley attacked from every angle. Arkansas's Darius Acuff Jr. kept the Razorbacks scoring but could never dent the margin — Arizona's cover probability against the 8.5-point spread climbed above 90% early in the second half and never came back. The Wildcats won by 21, covering by 12.5 in the most dominant performance of the Sweet 16.
