2026 March Madness First Round Preview

Thursday, March 19 & Friday, March 20

The bracket is set, the First Four is underway, and the real madness kicks off Thursday when 32 teams take the floor across four venues simultaneously. As always at BettorsWorld, our multi-timeframe predictive models have been run across every matchup we can lock in — and there are a few games worth watching very closely from a totals perspective.

One important note: four games are not covered in this preview. The Thursday Michigan game (Midwest 1-seed), Thursday’s BYU game (West 6-seed), Friday’s Florida game (South 1-seed), and Friday’s Tennessee game (Midwest 6-seed) all depend on the outcomes of First Four matchups currently being decided Tuesday and Wednesday in Dayton. Once those results are in, we can run those lines. Check back for updates.

The model predictions you’ll see below reflect the same framework we’ve used all season. It’s also worth noting upfront: these models tend to perform better in the regular season, when sample sizes are larger and schedule-adjusted efficiency metrics have more data to work with. The tournament introduces neutral-court dynamics, one-and-done pressure, bracket positioning, and matchup quirks that regular-season data doesn’t always capture cleanly. Use these as one input, not a crystal ball.

The One Trend Worth Tracking This Weekend

Before breaking down the games, here’s a pattern that’s paid off consistently over the last five years of first-round tournament action: unders in games where our model’s predicted total falls 5 or more points below the posted line. Tournament basketball tends to run slower than regular-season averages suggest — defenses tighten, pace slows down in close games, and the margin for predictive model error usually benefits the under side when there’s a significant gap. There won’t be many qualifying games, but the ones that meet the threshold are worth noting. We’ll flag them in the breakdowns below.

Thursday, March 19

Nebraska -13.5 vs. Troy | Total: 134.5 Model: Nebraska 76, Troy 68 (Total: 144)

Nebraska opened as a heavy favorite and the model agrees on the winner, projecting a Huskers win but a Troy cover. Model predicted total of 144 is well above the 134.5 line — a near-10-point gap — which actually points toward the over here rather than our under trend. Nebraska has never won an NCAA Tournament game in program history, which adds a layer of caution when talking about covering large spreads.

---

Louisville -7.5 vs. South Florida | Total: 163.5 Model: Louisville 82, South Florida 79 (Total: 161)

The model likes Louisville to advance but sees a tighter game than the spread implies. With a projected total of 161 against the 163.5 line, it’s close but doesn’t quite clear the 5-point threshold for our under angle.

---

Wisconsin -12.5 vs. High Point | Total: 166.5 ⬇️ Under Watch Model: High Point 84, Wisconsin 77 (Total: 161)

This is one of the most fascinating games of the opening round regardless of betting angle. High Point is 30-4 with the nation’s largest average scoring margin at 19.7 points per game and has won 14 straight. The Panthers aren’t a typical 12-seed. Our model actually flips the result entirely and projects a High Point upset — which may or may not prove correct — but more importantly for totals purposes, it projects a combined score of 161 against a 166.5 line. That 5.5-point gap qualifies as one of our under plays of the weekend. Wisconsin fires from three at a massive rate (33 attempts per game), and if High Point can limit transition opportunities, this one could stay well in the 150s.

---

Duke -27.5 vs. Siena | Total: 136.5 Model: Duke 75, Siena 61 (Total: 136)

The model and the market are nearly in perfect alignment on the total here. Duke cruises as the No. 1 overall seed, but if you’re looking for anything of note, Siena has been battle-tested in the MAAC. The model sees the Blue Devils winning comfortably — nothing surprising — but Cameron Boozer and company have dealt with injuries this season that could affect their ceiling in this region.

---

Vanderbilt -10.5 vs. McNeese | Total: 150.5 Model: Vanderbilt 76, McNeese 75 (Total: 151)

McNeese has made three consecutive NCAA Tournament appearances and the Cowboys are high-octane with high-major athleticism. The model projects an absolute dogfight — a one-point Vanderbilt win — making this potentially the most on-edge game of the opening round. If you’re looking for a potential 12-over-5 upset, McNeese has the profile. The model’s near-perfect alignment with the total (151 vs. 150.5 posted) doesn’t signal a lean either way.

---

Michigan State -15.5 vs. North Dakota State | Total: 143.5 Model: Michigan State 75, North Dakota State 72 (Total: 147)

The model projects a surprisingly competitive game here. North Dakota State won the Summit League at 27-7, and the model pegging this as a 3-point MSU win should give Spartans backers a moment of pause. The projected total of 147 is above the 143.5 line, a modest gap that doesn’t clear our threshold but edges toward the over.

---

Arkansas -15.5 vs. Hawai’i | Total: 161.5 Model: Arkansas 80, Hawai’i 78 (Total: 158)

Hawai’i’s first tournament appearance since 2016 doesn’t have the Rainbows playing spoiler according to the model, but it does see them keeping it close. A projected 3.5-point under gap (158 vs. 161.5) doesn’t quite cross our threshold, but the under still has some merit if the game plays tight throughout.

---

North Carolina -2.5 vs. VCU | Total: 155.5 Model: VCU 76, North Carolina 75 (Total: 151)

One of the true upset calls of the weekend — the model actually sides with VCU to eliminate North Carolina. The Tar Heels have dealt with the Caleb Wilson injury situation late in the season, and VCU has been one of the hottest teams in the country, losing just once since January 10. That kind of form in a one-and-done environment is dangerous. The projected total of 151 vs. the 155.5 line represents a 4.5-point under lean but doesn’t quite hit our 5-point trigger.

---

Saint Mary’s -2.5 vs. Texas A&M | Total: 148.5 Model: Saint Mary’s 80, Texas A&M 75 (Total: 155)

The Gaels are disciplined and methodical, but the model projects a faster-paced game than the market expects, with the combined score coming in at 155 against a 148.5 total — a 6.5-point gap in favor of the over. It’s not an under spot, but worth noting if you’re tracking totals.

---

Illinois -21.5 vs. Penn | Total: 149.5 Model: Illinois 83, Penn 69 (Total: 152)

Illinois wins but doesn’t cover according to the model. The Illini have been one of the more volatile teams late in the season — four of their last nine games went to overtime — but against an Ivy League opponent on a neutral floor, expect the talent gap to show. Penn earns the bid as the Ivy champion, having beaten Yale in an overtime classic in the title game.

---

Georgia -1.5 vs. Saint Louis | Total: 171.5 ⬇️ Under Watch Model: Saint Louis 85, Georgia 79 (Total: 164)

Another model upset — Saint Louis over Georgia — and this one comes with the single biggest totals gap of the weekend. The line at 171.5 is enormous for a first-round game between an 8 and 9 seed. Our model projects a combined score of 164, a 7.5-point gap well clear of the 5-point threshold. Saint Louis finished 28-5, is one of the hottest teams in the South, and the model believes in them here. The under at 171.5 is the strongest under signal of the entire opening weekend.

---

Gonzaga -18.5 vs. Kennesaw State | Total: 157.5 ⬇️ Under Watch Model: Gonzaga 85, Kennesaw State 67 (Total: 152)

A third qualifying under spot. Gonzaga wins this game — that’s not in doubt — but the model projects a combined 152 against the 157.5 line, a 5.5-point gap. Kennesaw State, appearing in just its second-ever NCAA Tournament, won the C-USA crown but finished the season 21-13 overall. Gonzaga’s defense limiting a lower-tier offense to the mid-60s fits the model’s projection well.

---

Houston -21.5 vs. Idaho | Total: 133.5 Model: Houston 77, Idaho 64 (Total: 141)

Houston wins, but the model sees a 7.5-point over gap (141 vs. 133.5). Idaho is a Big Sky program appearing in its first tournament since 1990, finishing just 21-14 on the season. The Cougars have made six consecutive Sweet Sixteens and should dispatch Idaho efficiently. The model leans toward the over here, not the under.

---

Friday, March 20

Kentucky -2.5 vs. Santa Clara | Total: 161.5 Model: Santa Clara 80, Kentucky 77 (Total: 157)

Another called upset — Santa Clara over Kentucky. The Broncos return to the tournament for the first time in 30 years behind a 26-8 season and 15-3 WCC record, and the model says they pull it off. Kentucky at 21-13 is a team the committee arguably overseeded. The projected total of 157 vs. 161.5 reflects a 4.5-point under lean — just short of our trigger — but if Santa Clara controls pace (which is their identity), the under has natural appeal.

---

Texas Tech -8.5 vs. Akron | Total: 155.5 Model: Akron 82, Texas Tech 78 (Total: 160)

A potential bracket-buster: the model projects Akron upsets Texas Tech. The Zips won the MAC at 29-5 and 17-1 in conference play, and the model sees them as the more explosive team in this matchup. The projected total of 160 exceeds the 155.5 line by 4.5 points — a slight lean toward the over.

---

Arizona -29.5 vs. Long Island | Total: 150.5 Model: Arizona 80, LIU 66 (Total: 146)

The 1-seed eliminates the 16. The model has LIU playing respectably but losing by 14. The projected total of 146 vs. 150.5 is a mild under lean but doesn’t clear 5 points.

---

Iowa State -23.5 vs. Tennessee State | Total: 148.5 Model: Iowa State 79, Tennessee State 66 (Total: 145)

Iowa State cruises. The Cyclones are 27-7 with one of the best defensive profiles in the country, and Tennessee State’s first tournament since 1994 is likely to be a brief visit. Model and line are very close on the total.

---

Purdue -23.5 vs. Queens | Total: 165.5 Model: Purdue 90, Queens 79 (Total: 169)

Purdue rolls, though the model projects it as a significantly higher-scoring game than the market does — 169 projected vs. 165.5 line. This is a 3.5-point over lean, driven largely by Braden Smith and the Boilermakers’ explosive offense.

---

Virginia -17.5 vs. Wright State | Total: 144.5 Model: Virginia 80, Wright State 72 (Total: 152)

The model actually projects a 7.5-point over gap here (152 vs. 144.5), one of the larger over signals of the weekend. Virginia, the ACC runner-up at 29-5, is a quality team but Tony Bennett’s program typically plays at a methodical pace — yet Wright State won the Horizon League and has shown offensive capability. The model’s over signal here is notable.

---

Alabama -12.5 vs. Hofstra | Total: 162.5 Model: Alabama 80, Hofstra 80 (Total: 160)

The model’s most eye-opening output of the entire slate: a predicted tie at 80-80, of course impossible in the actual game, but the signal is clear — this is too close for comfort. Hofstra, making its first tournament appearance since 2001 after winning the CAA, is no pushover. The model is essentially saying Alabama covers nothing and this could come right down to the wire. Fade that spread at your own risk. The total projection of 160 vs. 162.5 is a mild under lean.

---

Kansas -12.5 vs. Cal Baptist | Total: 134.5 Model: Kansas 68, Cal Baptist 67 (Total: 135)

Similar warning to the Alabama-Hofstra situation: Kansas wins by one point in the model. Cal Baptist won the WAC championship in their first year of eligibility and are 25-8. The model sees this as a potential massive upset — Cal Baptist covering a 12.5-point spread and possibly winning outright. The total of 135 is nearly exactly at the line.

---

St. John’s -9.5 vs. Northern Iowa | Total: 130.5 Model: St. John’s 68, Northern Iowa 65 (Total: 133)

The Johnnies win according to the model, but Northern Iowa could be the value play of the weekend. The Panthers won four games in four nights at Arch Madness — the first team ever to accomplish that feat — including wins over teams they had no business beating. Tristan Smith’s return from injury makes them more dangerous. The model’s 3-point win for St. John’s is far tighter than the 9.5-point spread.

---

Miami -2.5 vs. Missouri | Total: 150.5 Model: Miami 81, Missouri 74 (Total: 155)

Miami advances in the model’s projection. The total of 155 vs. 150.5 posted is a 4.5-point over lean — close to the threshold but not quite there.

---

Villanova vs. Utah State -1.5 | Total: 147.5 Model: Utah State 77, Villanova 73 (Total: 150)

The model sides with Utah State, which opened as a slight favorite and is 28-6 on the season. Both schools fit a similar profile of disciplined mid-major-style basketball with tournament pedigree. A low-key but well-matched game.

---

Clemson vs. Iowa -1.5 | Total: 130.5 Model: Iowa 71, Clemson 69 (Total: 140)

Iowa opened as a narrow favorite and the model agrees, projecting a 2-point Hawkeyes win. The model’s projected total of 140 vs. the 130.5 line is a significant over gap of 9.5 points — the largest over signal of the entire weekend. If you’re playing totals on Friday, this one is worth a look on the over side.

---

UCLA -5.5 vs. UCF | Total: 154.5 Model: UCLA 80, UCF 76 (Total: 156)

UCLA wins comfortably enough and the model closely mirrors the market on the total. Nothing stands out here beyond a fairly routine higher-seed advance.

---

UConn -18.5 vs. Furman | Total: 136.5 Model: UConn 76, Furman 66 (Total: 142)

UConn wins but doesn’t cover according to the model. We dosagree and think UCONN bounces back from their Big East loss to St Johns in a big way. Furman won the Southern Conference for the second time in three years but the talent gap is significant. The model projects an over gap of about 5.5 points, but this is primarily a coverage question — not a totals play.

---

Summary: Totals to Watch

The three qualifying under plays — Wisconsin/High Point, Georgia/Saint Louis, and Gonzaga/Kennesaw State — align with our historically strong trend of tournament unders when the model gap exceeds 5 points. The Georgia/Saint Louis total of 171.5 stands out as the biggest single under opportunity on the board this weekend.

As always, the tournament rewards discipline. There are a lot of games, a lot of noise, and a lot of bad public bets to be made over the next two days. Pick your spots, trust the process, and enjoy the madness.
