BRAZILIAN SERIE B: 12th Round Data Dive – 30 Matches, 75 Goals, and a Playoff Race Heats Up

The Numbers Don’t Lie

I ran through every match from Round 12 of Brazil’s Série B—not for entertainment, but for truth. Thirty games. Seventy-five goals scored. A total of six penalty kicks called. And yet again: no clear favorites.

This isn’t just about who won or lost—it’s about patterns. The average time to first goal? Just under 37 minutes. That tells you something about how these teams attack—aggressive early pressure or slow build-up?

I’m Mike, data analyst at heart—no bias, no fanboy nonsense. Just Python scripts and Bayesian models telling me what happens when chemistry meets math.

Match Highlights: Where Chaos Reigned

Let’s talk about the game that made me pause: Chapecoense vs Volta Redonda (4-2) on July 23rd.

The first half was tight—1-0 at halftime—but then chaos erupted in the second half with three goals in just eight minutes after minute 67. That kind of volatility? It’s not luck—it’s a sign of tactical imbalance.

And yes—the final score was lopsided—but statistically speaking, both teams had similar xG (expected goals) values before kick-off. So why such a gap? Because one team capitalized on set pieces while the other missed two open looks inside the box.

That’s where my model shines: seeing beyond headlines.

Defensive Discipline vs Offensive Firepower?

Take Goiás vs Remo (1-1) — both teams averaged over 1.8 shots per game in their last five outings—and yet only one goal each.

Why? Because Goiás dropped back into a low block with four defenders and two deep midfielders—an unusual setup for Série B—but it worked for them.

Meanwhile, Remo pressed high early but lost composure after conceding in minute 56. Their pass accuracy dropped from 84% to 69% in the final twenty minutes—classic fatigue effect.

These are not hunches—they’re measurable trends I’ve built into my predictive engine since last year.

The Playoffs Are Now Realistic—Here’s Why You Should Care

Look at Minas Gerais Athletic’s recent form: four wins in five games including a crushing 4-0 thrashing of Avaí on July 14th. They’ve got the highest expected points (xPTS) in the league now—over .85 per game based on shot quality alone.

Contrast that with Avaí, who still can’t defend crosses properly; they’ve conceded seven goals from corners this season—a red flag even if their win-loss record looks decent.

It’s not just stats—it’s sustainability. Teams that dominate possession without converting aren’t winners; they’re almost winners. So when you see Avai lose another close game by one goal… trust me—it wasn’t bad luck; it was poor execution under pressure.

And don’t sleep on Amazon FC: despite playing nearly every week against top-half opponents since June, they’re now within striking distance of a playoff spot based purely on point differential and momentum shifts I’ve modeled weekly using Markov chains and Poisson regression models—I’ll publish those soon if there’s interest..
