TOURNAMENT MODEL

Three-system composite model tracking all 64 remaining teams through the bracket. Win probabilities, per-game matchup analysis, and path-to-title projections — updated after each round.

KenPom NetRtg (50%): pace-adjusted efficiency margin · luck-corrected
Torvik T-Rank (25%): recency-blended · 30-day AdjO−AdjD weighted by game count
Massey Composite (25%): ensemble of ~100 computer rating systems · z-scored to KP units
Four Factors matchup: Oliver coefficients · schedule-adjusted · 85% composite + 15% stylistic
Simulation: 200,000-run Monte Carlo · β=1/11 · neutral site · R64 results incorporated
Methodology

How the model works: three rating systems blended into a composite, with luck adjustment and recency weighting. Per-game win probabilities add a four-factors stylistic layer. Results from completed rounds are incorporated via a margin-of-victory adjustment.

Composite Rating
01
KenPom Adjusted Net Rating — 50%
KenPom's pace-adjusted efficiency margin with a luck correction: KPadj = KPnet − luck × 0.30 × 10. KenPom's luck metric captures how much a team's record over- or underperformed its underlying efficiency in close games. Teams with positive luck (St. John's, Kansas) are adjusted downward; teams with negative luck (Ohio St., Tennessee) get a boost. The adjustment is modest — Pearson r between raw and luck-adjusted ≈ 0.96.
02
Torvik T-Rank, Recency-Blended — 25%
Torvik's opponent-adjusted net rating (AdjO − AdjD), blended between full-season and last-30-day results: w = min(0.80, recent_games / 15). At nine recent games (field median), the blend weights are roughly 60% recent / 40% full-season. This is the model's primary signal for teams that have improved or declined meaningfully in the second half of the year. Teams missing from the 30-day export fall back to full-season numbers.
03
Massey Composite — 25%
The Massey Ratings consensus — an ensemble of roughly 100 independent computer ranking systems (including Sagarin, Colley, and ~97 others) — published as an ordinal rank, then z-scored and rescaled to KenPom units so all three sources blend on the same scale. KenPom and Torvik each appear within the ensemble at minimal weight, so the three inputs are not fully independent, but the overlap is negligible. Final composite: 0.50×z(KPadj) + 0.25×z(TVblend) + 0.25×z(−MasseyRk).
Win Probability & Simulation
04
Per-Game Win Probability
Win probabilities use an 85/15 blend of the composite gap and a four-factors stylistic matchup margin: P = 1/(1+exp(−(0.85×ΔComp + 0.15×ΔMatchup) × β_eff)). The four-factors component uses Oliver coefficients on Torvik data — eFG% (1.37 pts/100 per 1%), turnover rate (1.02), offensive rebounding (0.68), free throw rate (0.29) — with an opponent-schedule adjustment applied to each team's raw stats before the matchup projection. Pace interaction uses the Oliver formula: game_pace = (paceA × paceB) / 67.7. The effective beta is pace-adjusted: β_eff = (1/11) × √(game_pace / 67.7).
05
Monte Carlo Simulation & Live Updates
200,000 full-tournament simulations from the current bracket state. All games treated as neutral site. β=1/11 is KenPom's empirically calibrated constant for D-I tournament games. After each completed round, teams' composite ratings are adjusted by a margin-of-victory signal: adjustment = surprise × 0.08, where surprise is actual margin minus expected margin. Winners receive the full adjustment; losers receive half. This keeps the model responsive to large upsets and dominant performances without overreacting to any single result.
TV Guide — Matchup Matrix
06
Schedule-Adjusted Four Factors
The matchup matrix in each TV Guide card shows opponent-adjusted four-factor projections for both teams. Raw season stats are scaled by a schedule-strength factor derived from a regression of each team's raw four factors against their KenPom rating: adj_factor = kpO / predicted_kpO_from_raw_stats. Matchup projections use the multiplicative formula: proj = adj_off × (opp_adj_def / avg), where avg is the D-I field mean. Oliver weights then scale each factor's contribution so the four-factor total matches the composite net rating edge — with a note shown when the four factors and composite point in opposite directions (indicating a Torvik/Massey signal that the raw four-factor data can't capture).
07
Value & Public Pick Comparison
Each card shows the model's win probability alongside the Yahoo Tournament Pick'Em public pick rate for that game. The edge pill (🔥 Strong value / ⚠ Overpicked) flags games where the model and public disagree by more than 5 percentage points. These signals are informational — they reflect how the bracket-picking public is weighing each matchup, not a betting recommendation. Data is from pre-tournament Yahoo pick rates and does not update in real time.
Data sources and coverage: All 68 tournament teams have complete data across KenPom, Torvik, and Massey — including all First Four participants. KenPom and Torvik data was pulled in the week before Selection Sunday. Massey Composite ranks were pulled on Selection Sunday. Round of 64 results have been incorporated via the margin-of-victory adjustment described above.

Model limitations: This model does not have access to injury reports, lineup changes, or other real-time information that may affect game outcomes. It is a pre-tournament snapshot updated for completed results, not a live prediction system. All probabilities are estimates with significant uncertainty — upsets are not just possible, they are expected.
Team Probabilities

200,000-iteration Monte Carlo with 85/15 four-factors matchup model. All 68 teams — First Four teams' odds scaled by their FF win probability. Sim Rk is fixed by simulation result; the # column updates dynamically with the current sort.

Composite = 0.50×z(KP luck-adj) + 0.25×z(TV recency-blended) + 0.25×z(−MasseyRk), rescaled to KenPom pts/100poss. Scores range roughly from −15 (bottom of field) to +37 (Duke). P(win) = 1/(1+exp(−(0.85×ΔComp+0.15×ΔMatchup)/11)). First Four teams ★ — downstream odds scaled by FF win probability.

Path Analysis

How difficult is each team's road to Indianapolis? For each team, we show their most likely opponent at every round (based on 100,000 simulation runs), the model win probability in that matchup, and a cumulative path difficulty score. Teams are ranked within each region by path difficulty — harder paths suppress title equity even for strong teams.

Path Difficulty = weighted average of (1 − win%) at each round, with later rounds weighted more heavily. Field range: ~78 (Duke, easiest draw) to ~200+ (16-seeds). vs Seed Avg = how much harder or easier this team's specific path is compared to other teams seeded identically — capturing whether a strong team landed in a brutal quarter of the bracket. Opponents shown are the most likely matchup based on simulation frequency; alternate opponents listed where another team has a meaningful chance of appearing.
TV Guide — Game-by-Game Scout Report

Per-game scouting reports for every NCAA Tournament matchup. Each card includes a projected score and win probability, a Matchup Summary in plain language, and a Matchup Matrix showing schedule-adjusted four-factor projections for both teams — with the pts/100 efficiency gap that drives the projected margin. Public pick rates are shown alongside model probabilities to flag value and contrarian spots. Filter by date, or hide completed games to focus on what's upcoming.
