By lining up each team's simulated championship probability against the market price, we can spot which contenders are being overvalued by their seeding and reputation, and which programs are quietly offering real betting value.

It's something our model excels at, cashing longshot futures in MLB and WNBA last season, so before the tournament tips off, let's dive into the Dimers March Madness Predictions to analyze the favorites' paths to the Final Four and which teams are poised to pull off bracket-busting upsets along the way.

For our full tournament predictions, check out the official Dimers March Madness bracket.

Best Bet to Win March Madness: Duke (+400)

Duke leads the way in the Dimers model at 35.7% to win the title, though fellow No. 1 seed Michigan is listed as the favorite on the sportsbooks.

This is notable for an umber of reasons, first of all, the clear value on the Blue Devils, with fair odds at just +180 for them to win it all.

Additionally, before the bracket was revealed, Duke, Michigan and Arizona all had a near identical championship probability around 21%. While Michigan also rose to 27.6%, it's Duke who's seen the biggest rise at more than a 50% increase, as well as their odds moving in a more favorable betting direction.

Despite an injury to guard Caleb Foster, our model still paints Duke as the top champion behind star Cameron Boozer, with our bracket pointing to a victory over Michigan in the National Championship on April 6.

Best Bet to Make the Final Four: Arizona Wildcats (-105)

You don't have to scroll far down the board to find Dimers' best bet to reach the Final Four.

In a tournament predicted to feature plenty of chalk results, including all four No. 1 seeds reaching the Final Four, Arizona stands out with nearly even money odds at a significant 66.5% probability to make it to the semifinals.

A fair sportsbook price would be almost -200 for this bet, which is longer than even favorites like Duke or Michigan to reach the same stage, and no other team besides those three squads even clears 50% to reach the Final Four, let alone a 60% probability.

Arizona was one of the best defensive units on a points per possessions basis this season and will be a force for any team that runs into them in the Midwest region of the bracket.

March Madness longshots and Cinderella teams

As we know, even in the age of NIL and favorites running through last year's tournament, there's always the possibility of a team surprising in the elimination-style nature of the March Madness CBB tournament.

Below you'll find a couple of longshots to win it all and some teams with an edge to advance through some of the earlier rounds of the tournament.

Cinderella bet: Illinois to win March Madness (+2500)

Dimers championship probability: 3.8%

Dimers' fair odds: +2530

Illinois winning it all would be one of the great upsets in tournament history, and the numbers reflect that as Dimers pegs their championship probability at just 3.8%, though notably their fair odds (+2530) nearly mirror the market price.

That makes them nota  value play, but fairly priced, which is not something you see any other tea, outside the top three overall probabilities.

The Illini have the offensive machinery to make noise behind freshman duo Keaton Wagler and David Mirkovic and their offensive rebounding keeps possessions alive. Winning six games against elite competition requires a complete team and Illinois may not check every box.

But anything can happen in March and a hot shooting stretch could carry them deep into the tournament for those looking to take a chance outside the big dogs.

Longshot bet: Purdue to reach Final Four (+800)

Dimers probability: 13.7%

Dimers' fair odds: +630

Purdue reaching the Final Four more than plausible in Dimers' predictions, assigning a 13.7% probability against fair odds of +630, making the +800 line at DraftKings a legitimate value play.

The Boilermakers boast the nation's second-best offensive efficiency, a battle-tested senior core led by Braden Smith, and the kind of veteran poise that typically thrives in March.

Dominant wins over Alabama, Texas Tech, and Auburn earlier this season showed flashes of a team that can beat anyone.

If this group locks in defensively and Fletcher Loyer shows up, the Boilermakers have the offensive firepower to grind through a tough bracket, even if they come up just short of reaching the title game.

Longshot bet: Louisville to reach Elite Eight (+550)

Dimers probability: 19.3%

Dimers' fair odds: +420

Louisville getting to the Elite Eight comes with a 19.3% probability, with fair odds of +420, meaning the market is offering us a great price at +550 on FanDuel.

The team has been missing standout Mikel Brown Jr. to injury and will be without him for the opening weekend at least, which could cap this team's ceiling.

Reinserting a star player mid-tournament after an injury is rarely seamless, and this team's track record in big moments gives pause as far as a deep run, but they could find themselves knocking on the door of the quarterfinals and get a great edge to do so here.

Longshot bet: Nebraska and Texas Tech to reach Sweet Sixteen (+330)

Dimers probability: Nebraska 53.5%, Texas Tech 49.3%

This is the only bet featuring two teams on this list, but both teams carry Dimers probabilities well above what the odds imply.

Nebraska checks in at 53.5% to reach the Sweet Sixteen, and Texas Tech at 49.3%, both presenting a standalone edge at odds of +115 and +145 respectively. Playing them both to punch their ticket gives you a +330 parlay on DraftKings.

Nebraska's case is compelling: their ball movement and floor spacing are elite and their defense tightened up dramatically over the final month of the regular season.

Texas Tech is trickier without JT Toppin, but the Red Raiders responded to his ACL tear by rallying together, and their perimeter shooting ability make them dangerous in win-or-go-home games.

Both teams have real vulnerabilities but our official Dimers March Madness bracket shows them in line for second-round upsets based on seeding with a mathematical edge to reach the Sweet Sixteen.
