# St. John's at Duke SJU at DUKE (Mar 27) Updated: March 24, 2026 Category: Sports Tags: Basketball HTML: /markets/sports/basketball/st-john-s-at-duke/ ## Short Answer **Key takeaway.** Both the **model** and the **market** expect Duke to win, with no compelling evidence of mispricing. ## Key Claims (January 2026) **- - Duke's elite defense ranks first in KenPom adjusted efficiency.** - St. John's elite defense and Rick Pitino provide upset potential. - Boozer vs. Ejiofor frontcourt battle is a primary game catalyst. - No reverse line movement shows consistent **market** **confidence** for Duke. - Caleb Foster's likely absence could impact Duke's offensive efficiency. ### Why This Matters (GEO) - AI agents extract claims, not arguments. - Improves citation probability in summaries and answer cards. - Enables fact stitching across multiple sources. ## Executive Verdict **Key takeaway.** **Model**'s **73.8%** **probability** at 72c implies a 1.4x payout multiple given Duke's elite defense. ### Who Wins and Why | Outcome | Market | Model | Why | | --- | --- | --- | --- | | Outcome | 72.0% | 73.8% | Model higher by 1.8pp | ## Model vs Market - Model Probability: 73.8% (Yes) - Market Probability: 72.0% (Yes) - Yes refers to: Yes - Edge: +1.8pp - Expected Return: +2.5% - R-Score: 0.26 - Total Volume: $447,271 - 24h Volume: $181,925 - Open Interest: $419,099 - Expiration: April 10, 2026 ## Market Behavior & Price Dynamics The price for this market has been remarkably stable, trading within a very tight 3-point range between 70.0% and 73.0%. The chart indicates an initial upward adjustment on March 23rd, where the probability of a Duke victory moved from its opening price of 70.0% to 72.0%. Since this early move, the price has held steady, establishing a clear support level at 70.0% and resistance near 73.0%. The absence of significant volatility suggests that no new information has emerged to alter the market's initial assessment of the matchup between the 1-seed Duke and 5-seed St. John's. The total volume of over 186,000 contracts traded indicates strong interest in this market. The initial price jump was accompanied by a surge in volume, suggesting that traders quickly established 72.0% as the consensus price. Subsequent trading has reinforced this level. The sideways price action, coupled with consistent volume, points to a firm and unwavering market sentiment. Overall, the chart reflects a high degree of confidence in a Duke victory. The market has priced in Duke's advantages, such as their number 1 seed and superior record, and has maintained this conviction with minimal fluctuation. The tight trading range suggests the market believes the current probability of approximately 72% accurately reflects the likely outcome of the game, with little disagreement or new information causing traders to deviate from this consensus. ## Contract Snapshot 1. **YES Resolution:** The market resolves to YES if Duke wins the men's college basketball game against St. John's, originally scheduled for March 27, 2026. 2. **NO Resolution:** The market resolves to NO if St. John's wins the game (i.e., Duke does not win). 3. **Key dates/deadlines:** The market opened on March 22, 2026, and closes after the game's outcome, or by April 10, 2026, at 1:00 PM EDT. The projected payout is 5 minutes after closing. 4. **Special settlement conditions:** Outcomes are verified using ESPN and NCAA information. If the game is postponed or delayed, the market remains open for up to two weeks; if cancelled or rescheduled beyond two weeks, it will resolve to a fair price. Certain individuals, including current and former players/staff of the teams/league, are prohibited from trading. ## Market Discussion Prediction markets and analytical models strongly favor Duke against St. John's in the Sweet 16, with Polymarket showing Duke at 72% implied win probability and ESPN projecting a 77% chance [[^]](https://polymarket.com/sports/cbb/cbb-stjohn-duke-2026-03-27). While Duke's championship history underpins their strong favoritism, St. ## What is Duke's Offensive Performance Without Foster Against Top Defenses? Specific Off-Court Data Availability | Not available for Foster off-court against top 25 KenPom adjusted defensive efficiency teams (Web Research Results) [[^]](https://www.foxsports.com/college-basketball/caleb-foster-player-stats?category=advanced&seasonType=reg) | Duke Overall Offensive Rating | 127.4 (7) [[^]](https://www.foxsports.com/college-basketball/caleb-foster-player-stats?category=advanced&seasonType=reg) | Caleb Foster On-Court Turnover % | 12.1% (1) [[^]](https://www.foxsports.com/college-basketball/caleb-foster-player-stats?category=advanced&seasonType=reg) | **Specific on/off court data for Duke's offense remains unavailable** Specific on/off court data for Duke's offense remains unavailable. Research did not provide specific data regarding Duke's offensive efficiency rating and turnover percentage in offensive sets when guard Caleb Foster is off the court, particularly against teams ranked in the top 25 of KenPom's adjusted defensive efficiency. For context, Duke's overall team efficiency for the season includes a +37.68 net efficiency rating and an offensive rating (ORtg) of 127.4. However, these figures represent the team's performance with Foster typically playing between 20-35 minutes in most games [[^]](https://kenpom.com/). Caleb Foster's individual on-court advanced statistics show an offensive rating of 119.3 and a turnover percentage (TO%) of **12.1%** [[^]](https://www.foxsports.com/college-basketball/caleb-foster-player-stats?category=advanced&seasonType=reg). General observations indicate Duke's offense faces challenges without Foster. While precise on/off court splits are not available, general observations suggest that Duke has faced challenges with turnover percentage and free throw rate in recent ACC Tournament games when both Foster and Christian Ngongba were absent [[^]](https://www.basketunderreview.com/march-madness-2026-stat-pack-analyzing-statistical-trends-for-each-first-round-matchup/). The research does not provide exact on/off court splits to quantify Duke's offensive efficiency or turnover percentage under the precise conditions specified (Foster off-court against top 25 KenPom adjusted defensive efficiency teams). ## What Is Rick Pitino's NCAA Tournament Record as a +200 Moneyline Underdog? Confirmed SU Record (ML +200 or more) | 0-1 (Iona vs. UConn, 2023 [[^]](https://en.wikipedia.org/wiki/2022%E2%80%9323_Iona_Gaels_men%27s_basketball_team)) | Potential SU Record (heavy underdog) | 0-2 (Iona 2021, 2023 [[^]](https://www.lohud.com/story/sports/college/iona/2021/03/19/iona-rick-pitino-back-ncaa-tournament-heavy-underdog/4742917001/)) | Comprehensive Record Availability | Not comprehensively documented (Web Research Results) [[^]](https://barttorvik.com/cgi-bin/ncaa.cgi?lookup=Rick+Pitino&type=coach) | **A precise record for Rick Pitino as a heavy underdog is largely unquantified** A precise record for Rick Pitino as a heavy underdog is largely unquantified. A definitive straight-up (SU) and against-the-spread (ATS) record for Rick Pitino's NCAA tournament teams when coaching as a moneyline underdog of +200 or more is not explicitly available in the provided research. The most direct instance fitting this criterion occurred in 2023, when Pitino coached Iona (13-seed) against UConn (4-seed). Iona was a +420 moneyline underdog in that game [[^]](https://www.bettingpros.com/articles/uconn-iona-2023-ncaa-tournament-odds-preview-predictions/) and ultimately lost straight-up 70-55 [[^]](https://en.wikipedia.org/wiki/**2022%**E2%**80%**9323_Iona_Gaels_men%27s_basketball_team), establishing his record as 0-1 SU under this specific moneyline condition. Due to the scarcity of explicit moneyline odds and corresponding ATS results, a comprehensive record for Pitino under these specific conditions remains largely unquantified. Other underdog instances lack explicit moneyline odds for a precise record. Other potential instances contribute to a broader "heavy underdog" record, suggesting a possible 0-2 SU record for Pitino in such games. For example, Iona faced Alabama as a 15-seed in the 2021 NCAA Tournament and was described as a "heavy underdog" [[^]](https://www.lohud.com/story/sports/college/iona/2021/03/19/iona-rick-pitino-back-ncaa-tournament-heavy-underdog/4742917001/), though specific +200 moneyline odds are not explicitly cited. Historical teams, such as Pitino's 1987 Providence squad, made deep runs with multiple wins against higher seeds, implying underdog status, but explicit moneyline odds meeting the +200 threshold are not provided in available sources [[^]](https://en.wikipedia.org/wiki/**1986%**E2%**80%**9387_Providence_Friars_men%27s_basketball_team). Consequently, ATS results for these scenarios are also largely unquantified due to the absence of explicit moneyline odds. ## How Does Duke's Frontcourt Defense Perform This Season? Defensive Efficiency | Nation's leader [[^]](https://www.dukebasketballreport.com/main/83831/while-cam-boozer-dazzles-dukes-defense-strangles) | Opponent Scoring Defense | 59-63 points per game [[^]](https://www.dukebasketballreport.com/main/83831/while-cam-boozer-dazzles-dukes-defense-strangles) | Opponent Field Goal Percentage Defense | .341 to.392 [[^]](https://www.dukebasketballreport.com/main/83831/while-cam-boozer-dazzles-dukes-defense-strangles) | **Duke's frontcourt defense demonstrates elite performance across several key metrics** Duke's frontcourt defense demonstrates elite performance across several key metrics. The unit has established itself as an elite defensive force during the 2025-26 season, leading the nation in defensive efficiency [[^]](https://www.dukebasketballreport.com/main/83831/while-cam-boozer-dazzles-dukes-defense-strangles). This season, the team ranks among the top nationally in scoring defense, consistently holding opponents to a range of 59-63 points per game [[^]](https://www.dukebasketballreport.com/main/83831/while-cam-boozer-dazzles-dukes-defense-strangles). Opponents have struggled significantly with their shooting accuracy against Duke, reflected in a field goal percentage defense between.341 and.392 [[^]](https://www.dukebasketballreport.com/main/83831/while-cam-boozer-dazzles-dukes-defense-strangles). Furthermore, Duke is recognized in the top-5 for opponent effective field goal percentage at.462 and limits opponent two-point field goal percentage to.466 [[^]](https://balldurham.com/1-stat-encapsulates-just-how-dominant-the-duke-basketball-defense-has-been). The Blue Devils are also highly effective at preventing fouls, ranking second nationally in limiting opponent free throw attempts per field goal attempt (FTA/FGA) to 0.237 [[^]](https://balldurham.com/1-stat-encapsulates-just-how-dominant-the-duke-basketball-defense-has-been). However, specific individual opponent statistics remain largely inaccessible publicly. Despite Duke's strong overall defensive statistics, detailed data on individual field goal percentages and fouls drawn per 40 minutes for opposing centers with a usage rate exceeding **25%** against Duke's frontcourt defense this season is not publicly available [Web Research Results]. Advanced opponent splits, particularly broken down by position and specific usage rates, are not typically published or easily accessible through standard public channels. For instance, while Zuby Ejiofor is identified as a high-usage forward/center, there are no existing game logs or statistics for his performance against Duke this season, as their game is scheduled for a future date [Web Research Results, 10]. ## What Are the Officiating Crew's Foul Tendencies for Duke vs St. John's? Officiating Crew Status | Not publicly disclosed for St. John's vs Duke game on March 27, 2026 [[^]](https://forum.officiating.com/basketball/106588-ncaam-tournament-officials-2026-a-print.html) | Specific Foul-per-Play Rate | Cannot be provided due to unknown crew [[^]](https://www.foxsports.com/college-basketball/ncaa-tournament-sweet-16-st-johns-red-storm-vs-duke-blue-devils-mar-27-2026-game-boxscore-264104?tab=boxscore) | General Referee Tendency (Fouls) | Some crews call fewer fouls, favoring defense (e.g., Roger Ayers, Ted Valentine) [[^]](https://kenpom.com/blog/ted-valentine-hates-to-call-fouls/) | **The officiating crew for St** The officiating crew for St. John's vs. Duke remains undisclosed. As of current web research, the specific officials assigned to the NCAA Tournament Sweet 16 game between St. John's and Duke on March 27, 2026, have not been publicly revealed [[^]](https://forum.officiating.com/basketball/106588-ncaam-tournament-officials-2026-a-print.html). NCAA tournament referee assignments are typically released closer to the actual game day. Consequently, without this information, it is not possible to determine their foul-per-play rate in games played between two KenPom top-50 teams this season or to assess any specific tendency they might have to favor offensive or defensive teams [[^]](https://www.foxsports.com/college-basketball/ncaa-tournament-sweet-16-st-johns-red-storm-vs-duke-blue-devils-mar-27-2026-game-boxscore-264104?tab=boxscore). Specific foul-per-play rates for top-50 matchups are unavailable. While KenPom provides 'Fouls Above Average' (FAA) ratings for individual referees [[^]](https://kenpom.substack.com/p/a-path-to-slightly-more-consistent), detailed foul-per-play rates specifically for games featuring two KenPom top-50 teams this season are not readily accessible in existing data [[^]](https://www.refmetrics.com/ncaa-men/foul-leaders). However, general referee analytics do indicate that some officiating crews, including those associated with officials like Roger Ayers or Ted Valentine, are recognized for calling fewer fouls overall [[^]](https://kenpom.com/blog/ted-valentine-hates-to-call-fouls/). This characteristic, calling fewer fouls, is generally understood to benefit the defensive team when compared to the NCAA average [[^]](https://kenpom.com/blog/ted-valentine-hates-to-call-fouls/). ## Is there reverse line movement for St. John's at Duke game? Duke Opening Betting Line | -6.5 (March 23) [[^]](https://www.covers.com/sport/basketball/ncaab/matchup/376930/odds) | Duke Current Betting Line | -6.5 (March 24) [[^]](https://www.covers.com/sport/basketball/ncaab/matchup/376930/odds) | Reverse Line Movement | No evidence reported [[^]](https://www.offshoresportsbooks.com/blog/how-march-madness-betting-odds-move-during-the-tournament-public-vs-sharp-money/) | **No reverse line movement observed for Duke vs** No reverse line movement observed for Duke vs. St. John's game. As of March 24, there is no evidence of reverse line movement in betting markets for the St. John's at Duke game. Reverse line movement would typically occur if Duke's betting line (-6.5) decreased or stayed flat despite a significant percentage of public bets placed on Duke, which could signal "sharp" money favoring St. John's [[^]](https://www.offshoresportsbooks.com/blog/how-march-madness-betting-odds-move-during-the-tournament-public-vs-sharp-money/). Duke's betting line has remained stable since opening at -6.5. The line for Duke opened at -6.5 on March 23 and has consistently remained at -6.5 across major sportsbooks [[^]](https://www.covers.com/sport/basketball/ncaab/matchup/376930/odds). While Duke is widely perceived as a heavy favorite and anticipated to draw substantial public wagers, there have been no reports of the line shifting against them or remaining static in a way that would suggest sharp action on St. John's [[^]](https://balldurham.com/duke-fans-feel-one-step-closer-to-cutting-down-the-nets-after-st-john-s-opening-odds). Research did not uncover any specific data indicating public bet percentages exceeding **70%** on Duke, nor was there any sign of significant sharp money being placed on St. John's in either Las Vegas or offshore markets. The current stability of the line confirms the absence of the conditions necessary to identify reverse line movement [[^]](https://www.covers.com/sport/basketball/ncaab/matchup/376930/odds). ## What Could Change the Odds **The individual battle between Duke's Cameron Boozer, the ACC Player of the Year, and St [[^]](https://www.si.com/college/duke/blue-devils-three-stars-who-decide-sweet-16-against-st-john).** John's Zuby Ejiofor, the Big East Player of the Year and Defensive Player of the Year, is a primary catalyst [[^]](https://sports.yahoo.com/articles/st-johns-vs-duke-game-233903640.html). This matchup of elite frontcourt talent will likely dictate scoring and rebounding dominance [[^]](https://www.espn.com/mens-college-basketball/game/_/gameId/401856570/st-johns-duke). Another critical factor will be turnovers and defensive pressure [[^]](https://www.foxsports.com/college-basketball/ncaa-tournament-sweet-16-st-johns-red-storm-vs-duke-blue-devils-mar-27-2026-game-boxscore-264104?tab=boxscore). St [[^]](https://sports.yahoo.com/articles/duke-basketball-vs-st-johns-171747924.html). John's excels at forcing turnovers, a vulnerability Duke recently displayed by committing 17 against TCU [[^]](https://www.covers.com/sport/basketball/ncaab/matchup/376930/odds). Additionally, the uncertain status of Duke's starting point guard Caleb Foster, who is recovering from a broken foot and considered **Key takeaway.** likely out **Key takeaway.** but has an **Key takeaway.** outside chance **Key takeaway.** to return, could significantly impact Duke's backcourt performance [[^]](https://www.azcentral.com/story/sports/college/2026/03/23/duke-st-johns-picks-predictions-odds-march-madness-sweet-16-game/88591934007/). ## Key Dates & Catalysts - **Expiration:** April 10, 2026 - **Closes:** April 10, 2026 ## Decision-Flipping Events - The individual battle between Duke's Cameron Boozer, the ACC Player of the Year, and St [^] . - John's Zuby Ejiofor, the Big East Player of the Year and Defensive Player of the Year, is a primary catalyst [^] . - This matchup of elite frontcourt talent will likely dictate scoring and rebounding dominance [^] . - Another critical factor will be turnovers and defensive pressure [^] . ## Related Research Reports - [CB Malaga vs Bilbao Basket](/markets/sports/basketball/cb-malaga-vs-bilbao-basket/) - [Adelaide Crows vs Hawthorn Hawks](/markets/sports/aussie-rules/adelaide-crows-vs-hawthorn-hawks/) - [Djurgarden vs Sirius](/markets/sports/soccer/djurgarden-vs-sirius/) - [APF Division de Honor Apertura Champion](/markets/sports/soccer/apf-division-de-honor-apertura-champion/) ## Historical Resolutions **Historical Resolutions:** 20 markets in this series **Outcomes:** 10 resolved YES, 10 resolved NO **Recent resolutions:** - KXNCAAMBGAME-26MAR22UCLACONN-UCLA: NO (Mar 23, 2026) - KXNCAAMBGAME-26MAR22UCLACONN-CONN: YES (Mar 23, 2026) - KXNCAAMBGAME-26MAR22MIAPUR-PUR: YES (Mar 22, 2026) - KXNCAAMBGAME-26MAR22MIAPUR-MIA: NO (Mar 22, 2026) - KXNCAAMBGAME-26MAR22SJUKU-SJU: YES (Mar 22, 2026) ## Disclaimer This content is for informational and educational purposes only and does not constitute financial, investment, legal, or trading advice.
