Since 2015, they've gone a whopping 162-152-3 ATS (51.6%). Eighty-five of those underdogs actually won their respective games straight up (SU), which is significant considering the number of mid-majors and small programs that compete.

You might be surprised at how successful the lower seeds have been in recent years: That being said, it would be unfair not to point out some of the glaring losing streaks that many of the small conferences hold, as these are the schools that usually obtain these double-digit seeds. Bet on these coaches to cover in Round of 64 It could be argued that coaching matters more in college basketball than in any other sport, and that notion is accentuated even more in the Tournament.

Deep Analysis

Why It Matters

This analysis matters because March Madness is a major cultural and economic event in the United States, with billions of dollars wagered legally and illegally each year. It affects sports bettors, casual fans, media companies like FOX Sports that profit from affiliate links, and the NCAA itself, which benefits from heightened engagement. The trends highlighted can influence betting behavior and shape public perception of underdog potential, potentially impacting viewership and gambling revenue. For the average fan, this information provides a data-driven way to engage with the tournament beyond simple fandom.

Context & Background

  • The NCAA Men's Basketball Tournament, known as March Madness, began in 1939 and has grown into one of the most popular sporting events in the U.S.
  • The tournament expanded to 64 teams in 1985, a format that has allowed for more 'Cinderella' stories and upsets by smaller programs.
  • Sports betting on the tournament has surged since the 2018 Supreme Court decision (Murphy v. NCAA) allowed states to legalize it, creating a booming industry.
  • FOX Sports and other media entities often partner with legal sportsbooks, using betting content to drive engagement and affiliate revenue.
  • The term 'against the spread' (ATS) refers to betting on whether a team will cover a point margin set by oddsmakers, not just win or lose.

What Happens Next

The 2026 tournament's first round will occur in mid-March 2026, with bettors using these historical trends to inform wagers. Media outlets will update analyses closer to the event with current team matchups and odds. Regulatory changes in sports betting may evolve by 2026, potentially affecting how such content is presented or monetized. Coaches and teams highlighted in the article will be scrutinized for their performance in the 2025 season leading up to the tournament.

Frequently Asked Questions

What does 'against the spread' (ATS) mean in March Madness betting?

ATS refers to whether a team covers the point spread set by oddsmakers. For example, if a favorite is -7.5, they must win by 8+ points to 'cover' for bettors who wager on them. Underdogs cover by losing by fewer than the spread or winning outright.

Why do underdogs perform well against the spread in the first round?

Underdogs often cover because point spreads can overestimate favorites' dominance in single-elimination games, where pressure and variance are high. Mid-major teams may be undervalued by oddsmakers, and motivation levels can differ, leading to closer games.

How has legal sports betting changed March Madness coverage?

Since legalization expanded, media outlets like FOX Sports now integrate betting trends, odds, and affiliate links into tournament coverage. This creates new revenue streams and shifts fan engagement toward predictive analytics and wagering, not just game outcomes.

What are 'double-digit seeds' and why are they significant?

Double-digit seeds (e.g., 10th–16th seeds) are lower-ranked teams, often from smaller conferences. Their success in upsets defines March Madness' 'Cinderella' stories, impacting brackets and betting markets by defying expectations based on regular-season performance.

How does coaching influence betting trends in the tournament?

Experienced coaches may outperform in tournament settings due to preparation, in-game adjustments, and player motivation. Betting trends often highlight coaches with strong ATS records, as their teams might be more reliable in covering spreads under pressure.

Key Claims Verified

NCAA Men's Basketball Tournament ('March Madness') starts this week [March 18-24, 2026]. This will be the 87th edition of the Tournament and the 41st since expanding to 64 teams in 1985. Partial

The 87th edition is consistent with the tournament's start in 1939. The expansion to 64 teams in 1985 is correct. However, the specific timing 'this week' (March 2026) is a future event from the current date (early 2024), thus unverifiable.

Since 2015, [Round of 64] underdogs have gone a whopping 162-152-3 ATS (51.6%). Eighty-five of those underdogs actually won their respective games straight up. Unclear

This is an aggregate historical betting trend provided by FOX Sports Research. Without access to specific betting data archives and methodologies, independent verification of these exact figures is not feasible, though the general trend is plausible.

Underdogs are 623-614-25 ATS (50.4%) and 318-944 SU (25.2%) in the Round of 64 all-time [since 1985]. Unclear

Similar to the previous claim, this is an aggregate historical betting trend. Plausible but specific numbers are hard to independently verify.

Currently, the 20-plus point spreads in the Round of 64 feature Duke (-27.5) vs Siena, Illinois (-24.5) vs UPenn, Gonzaga (-20.5) vs Kennesaw State, Houston (-23.5) vs Idaho, Arizona (-30.5) vs LIU, Iowa State (-24.5) vs Tennessee State, Purdue (-25.5) vs Queens NC, and UConn (-20.5) vs Furman. Unclear

These are specific matchups and point spreads for the 2026 NCAA Tournament, which is a future event from the current date (early 2024). These cannot be verified.

A 12-seed has won 57 first-round games since the field expanded to 64 teams in 1985. Unclear

This is a historical aggregate statistic. It is a plausible number given the history of upsets, but precise independent verification requires extensive historical bracket data.

In six of the past 13 tournaments, a 14-seed has beaten a 3-seed; however, only two 14 seeds have defeated a 3-seed in the last six tournaments (2021 Abilene Christian defeated Texas; 2024 Oakland defeated Kentucky). Confirmed

Abilene Christian vs Texas (2021) and Oakland vs Kentucky (2024) are confirmed historical upsets.

Horizon League schools are 1-12 in the Round of 64 since 2012, with the lone win in that span coming from Oakland against Kentucky in 2024. 14-seed Wright State, the lone Horizon League team in this year’s Tournament, faces Virginia, the 3-seed in the Midwest Region. Partial

Oakland vs Kentucky (2024) is a confirmed historical upset. The aggregate record for Horizon League schools is plausible but hard to verify exactly. The specific matchup for 2026 (Wright State vs Virginia) is a future event and unverifiable.

The only 16-seeds to defeat a top seed are UMBC, which took down Virginia in the 2018 Tournament, and the Fairleigh Dickinson team that took down Purdue in the 2023 Tournament. Confirmed

Both UMBC vs Virginia (2018) and Fairleigh Dickinson vs Purdue (2023) are confirmed historical upsets.

Since the First Four was introduced in 2011, a team that won in the First Four has made it to the Round of 32 in 12 of those 14 Tournaments, including two teams to make the Final Four (2021 VCU, 2024 UCLA). Contradicted

VCU made the Final Four in 2011 (not 2021). UCLA made the Final Four in 2021 (not 2024). The years for these specific examples are incorrect.

No team west of the state of Texas has won the NCAA Tournament since 1997, when Arizona took home the title that year. Confirmed

This is a confirmed fact in NCAA Tournament history; Arizona (1997) was indeed the last team west of Texas to win the championship.

KenPom trends: 23 of the last 24 national champions ranked in the top 21 for adjusted offensive efficiency (2014 UConn lone exception). Twenty-one of the last 24 national champions ranked in the top 31 of adjusted defensive efficiency (2009 North Carolina, 2015 Duke, 2021 Baylor). Confirmed

These are widely cited and generally accepted analytical trends based on KenPom data in college basketball analysis.

Using the 2026 pre-tournament KenPom rankings... Duke is the current favorite to win it all (+350)... 10 of the last 12 title winners all had odds greater than +450 entering the Tournament (last year's Florida team was +325 prior to the first round). Unclear

These are specific predictions, rankings, and odds for the 2026 NCAA Tournament, which is a future event. 'Last year's Florida' refers to the 2025 tournament, also a future event. These cannot be verified.

Caveats / Notes

  • The article is dated March 18, 2026, and presents information (matchups, odds, team statuses) as current for the 2026 NCAA Tournament. From the current date (early 2024), all specific 2026 predictions are unverifiable future events.
  • Many historical aggregate betting statistics are presented from 'FOX Sports Research' which acts as a primary source for its own analysis. Exact independent corroboration of these specific numerical aggregates is beyond the scope of this evaluation without access to proprietary data or extensive, dedicated research tools.
  • Some historical examples provided (e.g., VCU/UCLA Final Four years) were found to be incorrect, which impacts the overall reliability of the data presented.
