When a No. 15 seed faces a No. 2 seed in the NCAA Tournament, the spread is usually enormous—but does 25.5 points properly capture the gulf between No. 2 Purdue's elite efficiency and No. 15 Queens University's defensive struggles, or is this market number inflated by seed perception and blowout assumptions?
Queens University vs Purdue Betting Preview
The opening round of the NCAA Tournament tips Friday night at 7:35 PM ET from the Enterprise Center in St. Louis, where No. 2 seed Purdue enters as a massive 25.5-point favorite over No. 15 seed Queens University. The Boilermakers check in at #8 in the AP Poll and #13 in the Coaches Poll with a 27-8 record, while the ASUN champion Royals bring a 21-13 mark and an RPI of #138. The total sits at 163.5.
Purdue's efficiency profile is dominant—#2 nationally in adjusted offensive efficiency (132.6) and #35 in adjusted defense (99.7), producing a net rating of +32.9 that ranks #8 in the country. Queens University counters with a respectable #73 adjusted offense (116.1) but a glaring weakness at #326 in adjusted defense (118.1), yielding a net rating of -2.0. The 34.9-point net rating gap favors Purdue heavily, but the model projects this game closer to an 11.6-point margin—suggesting the market may be overvaluing the seed differential and undervaluing Queens' offensive capability.

The Matchup
The most decisive factor in this NCAA Tournament clash is the collision between Purdue's nation-leading adjusted offense and Queens University's porous defense. The Boilermakers rank #1 nationally in adjusted offensive efficiency at 131.6 per KenPom, fueled by elite ball movement—19.9 assists per game (#3 nationally) and just 8.9 turnovers (#5). Point guard Braden Smith orchestrates the attack with 8.7 assists per game (#2 in the nation), while Trey Kaufman-Renn provides interior balance with 13.9 points and 10.7 rebounds per contest. Purdue shoots 49.9% from the field (#14) and 37.9% from three (#20), with an effective field goal percentage of 57.6% (#12).
Queens University's defensive numbers tell a troubling story for NCAA Tournament survival. The Royals rank #326 nationally in adjusted defensive efficiency (118.1) and allow 82.9 points per game (#353). Opponents shoot 46.6% from the field (#308 in opponent FG%) and 35.4% from three (#293). The defensive rebounding is equally concerning—Queens ranks #300 in defensive rebounding rate at 33.0%, which will allow Purdue's #21-ranked offensive rebounding unit (36.3%) to generate second-chance opportunities. The model projects Purdue to score 83.5 points on 125.3 points per 100 possessions—well above their season average.
Queens University does bring offensive competency that could keep this game from spiraling into a 30-point blowout. The Royals rank #41 in offensive rating (119.9) and #17 in true shooting percentage (60.6%), matching Purdue's mark. They shoot 48.3% from the field (#33) and 56.7% effective field goal percentage (#16), led by Nasir Mann's 15.1 points per game. Jordan Watford distributes effectively with 3.9 assists, and the Royals turn the ball over just 10.7 times per game (#107). The issue is whether that efficiency translates against Purdue's #36-ranked adjusted defense, which allows just 70.1 points per game and holds opponents to 44.6% shooting.
Pace will be critical in determining whether this spread holds. Purdue plays at a glacial 63.9 possessions per game (#316 nationally), while Queens operates slightly faster at 69.3 (#67). The blended projection of 66.6 possessions favors Purdue's deliberate style, which could limit Queens' total scoring opportunities and make the 25.5-point spread more difficult to cover. However, the projected total of 155.3 points sits 8.2 points below the market's 163.5 number, suggesting the over is overvalued in a game where Purdue will control tempo and shorten possessions.
Tournament context matters here. No. 15 seeds are 11-152 all-time against No. 2 seeds, but the margin of defeat in those losses varies widely. Queens University's 0-4 record in Quadrant 1 games and 0-4 mark in Quadrant 2 contests reveals they haven't faced elite competition successfully this season. Purdue's 9-7 record in Q1 games shows they've been tested repeatedly in the Big Ten grind. The Boilermakers are 7-0 on neutral courts this season, while Queens is just 3-1. Experience also tilts heavily toward Purdue—2.486 years of average experience versus Queens' 1.312 years, plus a massive continuity edge (62.1% vs 36.6%).
Prediction
Purdue's elite offensive efficiency and Queens University's defensive deficiencies create a clear path to a Boilermaker victory, but the 25.5-point spread asks Purdue to dominate in a way that doesn't align with the projected possession count. The model sees an 11.6-point margin, suggesting 13.9 points of value on Queens University to cover. The Royals have enough offensive firepower to stay within 20 points if they can hit threes and avoid catastrophic turnovers against Purdue's patient attack. The total projection of 155.3 points also signals the under is the sharper play, as Purdue's slow pace and defensive discipline should keep this game in the 150s rather than pushing toward 170.
Projected Final Score: Purdue 83, Queens University 72
Best Bet: Queens University +25.5. The efficiency gap is real, but the market has overshot the likely margin in a controlled-pace NCAA Tournament game. The under 163.5 also merits consideration as a secondary play.
