The largest deficits overcome — ranked by how far behind the winner was at their lowest point.
The data shows 8–38 at the 6:43 mark of the first half. That is not halftime. There were 27 minutes of basketball remaining, and Duquesne trailed by 30. The win probability model — designed to temper early overconfidence — would have registered something functionally close to zero for the Dukes.
Duquesne won 79–77. Richmond scored 39 more points the rest of the game. Duquesne scored 71. The comeback required a 32-point swing over 27 minutes, then winning at the end by 2.
New Hampshire trailed 40–65 with 10:42 remaining in the second half. They won 88–82. That means they outscored Boston University 48–17 over the final 10 minutes — roughly 4.5 points per minute for New Hampshire while holding BU to under 2. Whatever broke for BU in that stretch was complete.
Belmont was the away team, trailing Drake 25–50 with 19:08 left in the second half — essentially the full second half ahead of them, on the road. Road comebacks are harder: no crowd, no home momentum. Belmont outscored Drake 53–26 over those 19 minutes to win 78–76 on a rival's floor.
UNC Wilmington trailed 21–45 at Stony Brook with nearly the full second half remaining. They won 75–71 as the away team — overcoming a 24-point deficit on the road. Stony Brook outscored them by 24 in the first half and managed just 26 points the rest of the way.
With 7:09 left in the first half, UNLV trailed Boise State 9–32 on the road. First-half comebacks require surviving the remainder of the half while still down, then completing the reversal over a full second half. UNLV won 86–83, outscoring Boise State 77–51 from that low point forward.
Illinois led 33–10 with 9:27 left in the first half at UCLA. The Bruins won 95–94. UCLA outscored Illinois 85–61 over the final 30 minutes. Both teams combined for 189 points; the outcome was decided in the final possession between two programs that produced one of the season's highest-scoring comebacks.
BYU's low point came at the 19:50 mark of the second half — the opening possession after halftime, trailing 22–44. The halftime deficit was 22 points. The Cougars then outscored Clemson 45–20 in the second half to win 67–64. A team that dominated the first half was outscored by 25 in the second and lost.
New Mexico trailed 18–40 at Fresno State with 5:20 left in the first half — 22 points, on the road, before halftime. Like the UNLV game, this comeback required surviving the first half while significantly behind, then completing the reversal over the full second half. New Mexico won 80–78.
East Carolina trailed 23–44 with 1:47 left in the first half — 21 points down with barely a minute before the break. They went into halftime still significantly behind, rallied in the second half, and won 73–70. Buffalo scored 44 in the first half and 26 in the second.
Georgetown, on the road at Providence, trailed 27–48 with 18:32 remaining. The Hoyas won 81–78, outscoring Providence 54–30 over the final 18 minutes to complete the road comeback — one of ten games this season where a team won after trailing by 21 or more.
