The Phillies have a 9-9-9 Challenge box for the Postseason 😭

It comes with 9 "fun size" hot dogs and 9 "petite" beers, and even features a scoreboard to keep track of your progress 🤣

Two photos of the Phillies' 9-9-9 Challenge box. It features 9 mini hot dogs and 9 small glasses partially filled with beer.

We can use xG to compute post-hoc win-draw-loss probabilities.

Our new blogpost shows MCMC's estimates of these probabilities are unstable, computing them exactly is faster than approximating them, and MCMC's runtime strongly depends on its implementation.

Expected goals and the Monte Carlo Trap

On a team level, xG is often used to assess the quality of the goal scoring opportunities that a team creates and concedes. That is, it…

paradox, you say

Research reveals a paradox: the more people understand AI, the more hesitant they may become to embrace it.

New #CMSAC #SportsAnalytics paper on evaluating change of direction in the #NFL by myself and @stat-ron.bsky.social

Spoiler alert: DK Metcalf displays straight-line, less agile movement, while George Pickens exhibits erratic, more variable directional movement.

NEW with @simonkuper.bsky.social:

The prevailing narrative around increased injuries and player workload in elite football is wrong.

Players don’t play any more football than in the past. What has changed is a sharp rise in intensity of play.

Not more minutes, but each minute exerts more load.
