March Madness Betting Trends: 88% of Final Four Teams Meet THIS Criteria

The Numbers Behind the Madness: How to Pick a Winning Bracket

March Madness. The most thrilling, unpredictable, heart-stopping event in sports. Each year, millions of fans fill out their brackets, searching for the perfect balance of logic and luck. The buzzer-beaters. The Cinderella stories. The heartbreak and the triumph.

Yet, buried beneath the madness, there is a method. A pattern. A formula that, while not foolproof, has consistently pointed the way to success. And it all starts with balance.

The Key to the Final Four: Balance Wins in March

Over the past two decades, 88% of Final Four teams have shared one crucial trait: they ranked in the top 50 in both adjusted offensive and defensive efficiency (per KenPom). That’s the magic number—if a team is elite on one side of the ball but lacking on the other, history suggests they’re vulnerable.

A few top teams this year don’t quite fit the bill:

• St. John’s (65th in offense)
• Kentucky (56th in defense)
• Purdue (63rd in defense)
• Missouri (73rd in defense)
• BYU (68th in defense)

When choosing your Final Four, look for balance. But also, look for greatness. Nearly 80% of Final Four teams have ranked in the top 10 in either offense or defense.

So, who fits the mold this year?

Teams That Fit the Final Four Formula

South Region:

• Auburn (2nd offense / 12th defense)
• Michigan State (27th offense / 5th defense)
• Iowa State (20th offense / 9th defense)
• Texas A&M (44th offense / 7th defense)

This bracket is loaded. Auburn profiles as the best all-around team here, but Iowa State is built for tournament success.

East Region:

• Duke (3rd offense / 4th defense)
• Alabama (4th offense / 32nd defense)

Duke looks like the best bet here, with a balanced and elite team that could cut down the nets.

Midwest Region:

• Houston (10th offense / 2nd defense)
• Tennessee (18th offense / 3rd defense)
• Gonzaga (9th offense / 29th defense)

Gonzaga, often overlooked, could be a sleeper to emerge from this group.

West Region:

• Florida (1st offense / 10th defense)
• Texas Tech (6th offense / 37th defense)
• Maryland (28th offense / 6th defense)

The West is the weakest region, but Florida, with the top offense in the nation, has the clearest path.

The National Champion Blueprint

If making the Final Four is about balance, winning a national championship requires dominance.

Since 2002, 95% of national champions ranked in the top 21 in offensive efficiency and 95% ranked in the top 37 in defensive efficiency before the tournament.

That leaves us with a very exclusive club:

1. Duke (1st overall, 3rd offense, 4th defense)
2. Florida (2nd overall, 1st offense, 10th defense)
3. Houston (3rd overall, 10th offense, 2nd defense)
4. Auburn (4th overall, 2nd offense, 12th defense)
5. Tennessee (5th overall, 18th offense, 3rd defense)
6. Alabama (6th overall, 4th offense, 32nd defense)
7. Texas Tech (7th overall, 6th offense, 37th defense)
8. Gonzaga (9th overall, 9th offense, 29th defense)
9. Iowa State (10th overall, 20th offense, 9th defense)
10. Wisconsin (13th overall, 13th offense, 27th defense)
11. Arizona (14th overall, 12th offense, 33rd defense)

This is the deepest field of championship-worthy teams in recent memory.

The Red Flags: Teams That Don’t Fit the Criteria

Be careful when picking these teams to go far:

• St. John’s (65th in offense)
• Missouri (73rd in defense)
• Kentucky (56th in defense)
• Texas A&M (44th in offense)
• Purdue (63rd in defense)
• Michigan (47th in offense)
• Kansas (48th in offense)

History tells us teams with major weaknesses rarely make deep runs.

The Best Tournament Field We’ve Ever Seen?

KenPom’s adjusted efficiency ratings suggest this might be the strongest collection of top teams in tournament history:

1. 2025 Duke – 38.16
2. 2015 Kentucky – 37.43
3. 2021 Gonzaga – 36.62
4. 2025 Florida – 36.16
5. 2025 Houston – 35.44
6. 2025 Auburn – 35.05

March Madness is defined by chaos. By upsets. By the unthinkable becoming reality. But if you want to give yourself the best shot at winning your bracket, follow the numbers. Balance wins in March. Defense travels. And history has a way of repeating itself.

This year’s tournament? It might just be the best we’ve ever seen.
