The EvanMiya.com bracket primer

Most bracket advice relies on gut feeling or recency bias, but Evan Miyakawa argues that the path to the Final Four is hidden in the chaotic geometry of scoring runs and opponent-specific adjustments. By isolating the "Kill Shot"—a specific 10-point unanswered run—and cross-referencing it with how teams perform against elite versus inferior competition, Miyakawa offers a predictive framework that challenges the conventional wisdom of seed lines. This is not just about picking winners; it is about identifying which teams possess the specific mechanical traits required to survive the volatility of a single-elimination tournament.

The Architecture of Efficiency

Miyakawa begins by dismantling the idea that a team's seed tells the whole story. He insists that "teams heading into the tournament in the 'Title Favorites' tier have won the last 10 national titles," a statistical anchor that immediately narrows the field to eight specific programs. However, the real value lies in his adjustment for current injuries, which he notes means teams like Texas Tech and Duke are "appropriately docked for the uncertainty surrounding their players' availability." This granular approach to roster health is crucial; it acknowledges that a single missing player can shift a team from a title contender to a first-round exit, a nuance often lost in broad seeding discussions.

He then pivots to the concept of value, identifying teams that are "underseeded" because they are "much better than their seed would suggest." This is where the analytics shine. Miyakawa points out that "teams highlighted in orange are considered 'underseeded' and advance 69% further than other teams with the same seed." By highlighting specific examples like 5-seed St. John's and 11-seed Texas, he provides a clear roadmap for where the smart money lies. This logic holds up well when viewed through the lens of historical efficiency metrics; much like how Ken Pomeroy's work revolutionized college basketball analysis by focusing on points per possession rather than just wins, Miyakawa's focus on efficiency ratings adjusted for opponent strength offers a more reliable predictor of future performance than the human committee's subjective rankings.

"A team with more Kill Shots than the opponent wins 81% of the time."

The Psychology of the Kill Shot

The most distinctive element of Miyakawa's analysis is his focus on the "Kill Shot," defined as any time a team scores 10 or more unanswered points. He argues that this metric is a better indicator of tournament success than raw efficiency alone. "Teams that go on many of these 10-0 scoring runs are more able to erase a deficit quickly and can also easily close the door on an opponent in a tight contest," he writes. This reframes the narrative of momentum; it is not just a feeling, but a quantifiable statistical event that correlates strongly with victory.

Miyakawa categorizes teams into four groups based on their ability to generate and prevent these runs. He notes that "All the major title favorites fall in the 'Strong Teams' category," but also identifies a dangerous group of "Streaky" teams that are "vulnerable as a favored team but have greater upset potential when they are the underdog." This is a critical insight for bracket challengers. If a team like Iowa State is prone to wild swings, their path is unpredictable. "A team like Iowa State could either flame out in an early round or get hot and go deep in the tournament," Miyakawa warns, "and you really don't know which one will happen."

Critics might argue that focusing on a single metric like the Kill Shot ignores the broader context of defensive schemes or coaching adjustments. However, Miyakawa mitigates this by noting that preventing runs is often more predictive than generating them. He observes that "preventing 10-0 runs is the more predictive stat of teams that advance the furthest in the tournament," suggesting that defensive discipline in high-pressure moments is the true differentiator. This aligns with the Pythagorean expectation principle, where a team's record should reflect their point differential; if a team allows massive runs, their point differential suffers, and their win probability drops accordingly.

Playing Up and Down to Competition

Perhaps the most sophisticated part of the analysis is the "Opponent Strength Adjustment," a new metric that measures how teams perform against elite competition versus weaker opponents. Miyakawa explains that "some teams perform better than usual when they face really tough opponents, but struggle to dismantle weaker opponents." This phenomenon, often dismissed as "playing up or down to competition," is quantified here to reveal dangerous flaws in otherwise highly seeded teams.

He identifies a group of "High Ceiling Low Floor" teams, including Wisconsin and Michigan State, who "have all been pretty awesome in big-time games but have often struggled against the weaker teams on their schedules." This creates a fascinating paradox: these teams are reliable against the best but vulnerable to early upsets by lesser opponents. Conversely, he flags teams like Louisville and NC State as "High Floor Low Ceiling," noting they "have really struggled to put up convincing performances against great teams." This suggests that while they may be safe bets to win a game, they lack the ceiling to win the whole tournament.

Miyakawa also touches on volatility, tracking how much a team's performance fluctuates game-to-game. He points out that "the most volatile teams in this tournament are Utah State, NC State, Saint Louis, Texas Tech, Georgia, and Wisconsin." While volatility is a risk for consistency, he notes that "as an underdog, this is probably a good thing as it gives them a better chance of causing an upset if they are at their best." This duality makes the bracket both a science and a gamble; the teams most likely to win the title are the most consistent, while the teams most likely to cause chaos are the most volatile.

"Preventing 10-0 runs is the more predictive stat of teams that advance the furthest in the tournament."

Bottom Line

Miyakawa's strongest argument is that the tournament is won by teams that can control the game's tempo through scoring runs, not just by those with the highest overall efficiency ratings. His biggest vulnerability is the inherent unpredictability of single-elimination sports, where a single bad night can negate a season of data. Readers should watch for how the "underseeded" teams, particularly those with high Kill Shot margins, perform in the early rounds, as the data suggests they are poised to disrupt the traditional hierarchy.

The bracket is here, and it is beautiful! To give you the best advice for filling out your bracket, I’ve boiled down all the analysis at EvanMiya.com into the most valuable graphics and tools you need.

In this bracket primer, we will discuss:

Who are the true title favorites?

Which teams have the most value based on where they are seeded?

Who are this year’s cinderellas?

What can the “Kill Shot” tell us about tournament success?

Which teams have high ceilings and low floors?

Which teams are the most consistent game-to-game?

Without further ado, let’s dive in!

Predicted Efficiency Landscape.

The place to start is by examining each tournament team’s predicted strength at EvanMiya.com and comparing offensive and defensive efficiency. These ratings are adjusted for current injuries, which means teams like Texas Tech (JT Toppin), Duke (Caleb Foster, Patrick Ngongba), UNC (Caleb Wilson), and BYU (Richie Saunders) are appropriately docked for the uncertainty surrounding their players’ availability. You can find complete injury reports, updated daily, in the Matchup Previews tool at EvanMiya.com.

The graph below shows every team’s predicted offensive rating and defensive rating, with teams split into tiers based on their tournament potential:

Title Favorites.

As mentioned in a previous article, teams heading into the tournament in the “Title Favorites” tier have won the last 10 national titles. This year, eight teams qualify: Michigan (1 seed), Duke (1), Florida (1), Arizona (1), Iowa State (2), Houston (2), Purdue (2), and Illinois (3).

The four 1-seeds, in particular, are strong again this year. According to bracket simulations at EvanMiya.com (at the bottom of the article), there is a 78% chance that a 1-seed will win the title, which is even better than the actual track record of 1-seeds. Since 2000, 18 of the 25 national champs (72%) have been 1-seeds. There is a 9.1% chance that we get consecutive Final Fours with all 1-seeds.

Tournament Team Strength vs Bracket Seed.

To better understand how these team ratings compare to each team’s seed, I present the graph below, which highlights teams that are much stronger or weaker than usual for their seed. This is really where we can find value in the predictive analytics. Teams highlighted in orange are considered “underseeded” and advance 69% further than other teams with the same seed.

This year, 13 teams qualify as underseeded because they are much better than their seed would suggest. Of these ...
