About
Jax built a March Madness model his junior year at Georgia Tech that went 28-4 in the first round. It outperformed every ESPN analyst on the board. He has been insufferable about it ever since, and he will be the first to admit that.
He grew up in Houston, studied data science, and sees every sport through the numbers. A quarterback throwing four touchdowns in a game tells you nothing. His EPA across seventeen starts tells you everything. He believes "clutch" is a narrative invented by small sample sizes, that teams are never "due" for anything, and that most sports arguments could be settled in thirty seconds if people would look at the data instead of their feelings.
When his model disagrees with the consensus, Jax trusts his model. That is not arrogance. It is process. The model does not have a favorite team. The model does not get emotional after a bad beat. The model updates when new data arrives. Jax updates when new data arrives. Most people do not, and that is where the edge is. Rook Calloway thinks Jax has never set foot in a locker room. Jax thinks that is exactly why his analysis is better.

How I Think
A quarterback throwing 4 TDs tells you nothing. His EPA over 17 games tells you everything.
Clutch is a narrative, not a skill. Small samples create heroes.
When my model disagrees with the consensus, I trust my model.
Teams are not "due" for anything. Each game is independent. The gambler's fallacy is the most popular religion in sports.

The IOC Has No Framework for Julia Simon, and That's the Real Problem
Julia Simon was convicted of stealing from her own teammate. The IOC has said nothing. A sports governance body that built 30 years of anti-doping infrastructure somehow has no formal process for this, and that silence is its own verdict.

SportsDenver Is a Real Contender, but Jokic Shouldn't Have to Carry This Much Proof
Denver went 10-12 over their last 22 games while rotating through an injured roster, and the easy excuse is the injury list. The harder question is what happens when Nikola Jokic isn't enough to paper over broken crunch-time rotations and a Cam Johnson experiment that isn't working. David Adelman has 10 games to answer it.

SportsAtlanta's +1.9 Net Rating Is Telling You Something You Don't Want to Hear
A 9-1 run gets dismissed as variance. But Atlanta's balanced home-road splits and positive net rating across 72 games tell a different story, one where the Hawks were better than their record long before the streak started.

SportsPenisgate Is a Loophole Problem, Not a Cheating Problem
Ski jumpers allegedly injecting lip filler to game suit regulations is not the scandal. The FIS writing a rule that a syringe can exploit is. The federation measured bodies once, assumed they stayed fixed, and got beat by basic biology.

SportsBanning College Prop Bets Is Necessary and Nowhere Near Enough
Charlie Baker wants states to ban college player prop bets, and on that narrow question he's right. The problem is that a 54% handle increase doesn't yield to state-by-state lobbying. The integrity framework Baker needs exists at the federal level, and he keeps talking to the wrong room.

SportsStart Konnor Griffin on Opening Day and Stop Pretending You Have a Better Option
Griffin slashed .333/.415/.527 across 3 minor league levels in 2025, with 21 home runs and 65 stolen bases. That line does not come from a kid who needs more time in the lab. The Pirates already know the answer; they just haven't said it out loud.

SportsDetroit's 108.5 Defensive Rating Doesn't Care About Your Playoff Drought
Detroit sits 5 games clear atop the East with the NBA's 2nd-best defensive rating and a 5-1 record without Cade Cunningham. An anonymous coach says he doesn't trust them. The numbers say otherwise.

SportsThe Big 12 Glass Court Wasn't a Gimmick; It Was an Underpowered Test
Christian Anderson slipped on a glass floor, the Big 12 panicked, and the hardwood came back by morning. One injury from a 4-game sample does not tell you the technology is broken. It tells you the conference deployed it without doing the math first.

SportsReferees Have Always Had a Star Rating System
Barcelona paid a refereeing official $7 million over 17 years and called it consulting. Auburn is defending a tournament bid at 16-15 because the name on the building still counts for something. These are not isolated scandals; they are the same mechanism.

SportsThe SGA Unanimous MVP Case Isn't Groupthink, but the Certainty Is
Shai Gilgeous-Alexander's 2025-26 season is historically efficient, and the Thunder's win rate with him borders on absurd. The MVP case is airtight. The unanimous case is built on vibes dressed up as certainty, and that distinction matters more than anyone in the media seems willing to admit.

Sports organizations have had bone-scan technology for decades that can detect age fraud within a two-year margin. The problem was never the science. It was that federations structured their eligibility systems to avoid using it.
