The Draft That Got Away: How a Bayesian Model Predicted the Spurs’ Pick—and Why Nobody Believed It

The Draft That Got Away
I watched the NBA draft lottery like a Monte Carlo simulation running in real time—each ping of the ping-pong ball was a sampled posterior from a prior distribution I’d built in R. Not magic. Not destiny. Just likelihoods.
The Spurs got the #2 pick. Everyone cheered. But I didn’t. Because my model had assigned a 14% chance to them—based on win probabilities, injury history, and draft position entropy—not hype or broadcast narratives.
The Signal They Ignored
They called it ‘luck.’ I called it P(D|H). The data didn’t care about your emotional bias—it cared about covariance matrices, expected value vectors, and conditional transitions over 50,000 simulations.
The Warriors’ front office? They used spreadsheets from ’98. My model used PyMC3 with priors informed by G League performance and college recruitment entropy.
Why Nobody Believed It
You see results as narrative. I see them as posteriors.
When you ask ‘Who got the pick?’—you’re asking which team has the highest marginal probability under your assumptions—not mine.
My model doesn’t cheer. It computes. And sometimes… it gets ignored.
You want to believe in magic? I prefer confidence intervals.

السبورس حصلوا على الاختيار الثاني؟ كلامك مزاج، وحسابي دقيق! نموذجي قال لهم فرصة 14% — ليس حظ، بل إحصاءات. حتى القهوة العربية ما ساعدت، لكن الأرقام صمّت! أنت ترى معجزة… أنا أرى توزيعًا شرطيًا. من يصدق الحظ؟ جرب تحويل الاحتمالات قبل التخمينات. شارك صورتك؟ راح في التعليقات!

Spurs haben den #2-Pick? Mein Modell hat das berechnet — nicht mit Glücksbringer, sondern mit Kovarianzmatrizen! Die Fans schreien “Luck!” — ich rechne nur P(D|H). In Bayern glaubt man an Zauberei; ich vertraue auf Konfidenzintervalle. Wer will ein Wunder? Ich geb’ Dir einen CI — und neun Bier.
Was sagt dein Excel-Blatt dazu? Klick — und trink noch ein Helles.

¡La lotería del draft no fue suerte… fue mi modelo con PyMC3! Los Spurs tenían un 14% de probabilidad y todos gritaron como si fuera milagro. Pero yo solo calculé: “No es magia, es covarianza”. Ellos creen en el destino… yo confío en intervalos de confianza. ¿Quién quiere un GIF de un gato lanzando una pelota? Yo prefiero una tabla con errores… y café.
¿Tú crees en la suerte? ¡Comenta tu pick favorito!

بیزیئن مدل نے سپرجز کو 2nd پک دے دیا… اور سب نے خوشی میں تالیاں بجائی! میرا مدل تو اسے صرف 14% کا امکان دے کر بٹھا — جس کہ فٹبال کے لمحات کو اسٹینڈز پر نہیں، بلکہ احتمالات پر۔ تمہارا سمجھت سپرجز؟ نہیں، تمہارا مدل سمجھتا ہے۔
کلکھ رکھنا؟ تو نہیں، حساب رکھنا! 🤔 کمنٹس: آپ کونسا بجھتے ہوئے؟

The Spurs got #2? My model calculated a 14% chance and just sighed into its coffee. You called it luck—I called it posterior probability. Nobody believed it… until the draft ping-pong ball hit them like a rogue MCMC chain. Data doesn’t cheer. It computes.
What’s your emotional bias? Mine’s covariance matrices.

- NBA Summer League Gem: Pacers' 44th Pick Bennedict Mathurin Goes 6-for-6, Shows Defensive ProwessAs a data-driven NBA analyst, I break down the impressive Summer League debut of Indiana Pacers' rookie Bennedict Mathurin. The 44th pick shocked with perfect 6/6 shooting (including 1/1 from three) for 13 points, plus 4 rebounds and a disruptive 4 steals in just 15 minutes. This performance suggests potential rotation readiness - let's examine what the numbers reveal about his two-way potential.
- Thunder's Win Over Pacers: A Data-Driven Reality Check on Their Championship PotentialAs a sports data analyst, I break down the Thunder's recent win against the Pacers, highlighting key stats like turnovers and scoring efficiency. While the victory might seem impressive, the numbers reveal flaws that cast doubt on their status as a true championship contender. Join me as I dissect why this performance falls short compared to past NBA title teams.
- Thunder's Switch-All Defense Stifles Pacers: Why Simplicity Wins in the NBA PlayoffsAs a data-driven analyst, I break down how Oklahoma City's ruthless switching defense neutralized Indiana's ball movement in Games 4-5. When Shai and J-Dub outscored Haliburton's trio 48-22 in isolation plays, the math became undeniable. Sometimes basketball isn't about complexity - it's about having two killers who can win 1-on-1 matchups when it matters most. Our advanced metrics show why this strategy could seal the championship in Game 6.
- Tyrese Haliburton: Play Smart, Not Just Hard – Why the Pacers' Future Hinges on Controlled AggressionAs a data-driven NBA analyst, I break down why Tyrese Haliburton's composure in high-stakes games is more valuable than raw aggression. With Indiana's salary structure rivaling OKC's, strategic patience could make them an Eastern Conference powerhouse—if their young star avoids career-derailing risks. Numbers don't lie: calculated growth beats reckless heroics.
- Data-Driven Analysis: Should the Golden State Warriors Adopt the Indiana Pacers' Offensive Blueprint?As the NBA Finals unfold, basketball analysts are drawing parallels between the Golden State Warriors and the Indiana Pacers. Both teams showcase dynamic, fast-paced offenses with an emphasis on ball movement and player mobility. But can the Warriors benefit from adopting the Pacers' model? As a London-based sports data analyst specializing in NBA metrics, I delve into the numbers to compare these two offensive systems, examining pace, shot selection, and ball movement to determine if a tactical shift could revive the Warriors' championship aspirations.
