1️⃣ Pressing triggers

▫️By focusing on the opponent's pass before a 1st pressing action in a sequence, it's possible to separate different triggers

👇 The graphic shows an example, with the 8 triggers that I defined

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 🤣

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…

NEW with @simonkuper.bsky.social:

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

Too many March Madness references for me to delay posting this any longer!
