Isaiah Zagar made Philadelphia, and in turn the world, a more beautiful place to live. May his memory be a blessing.

NBC ran a piece where Mary Carrillo went to Norway to find out why they're so good at the Winter Olympics and i was yelling BECAUSE IT'S COLD THERE

then she went to a little tiny ski jump for kids and was like "it's free, equipment is provided, & they don't emphasize results"

and i was like.
oh!

What to Do When Your Season Isn't Technically Over? โ€œOh god, do I have to watch my awful team win just enough games to never draft an elite talent?โ€

Is it bad to be thinking about the draft after 10 Vikings games? Asking for a friend

๐Ÿงต Thread: I recently explored a few ideas to analyze a team's press in more detail ๐Ÿ‘‡

โ–ซ๏ธBy focusing on the opponent's pass before a 1st pressing action in a sequence, it's possible to separate different triggers

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, itโ€ฆ

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.

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

arxiv.org/pdf/2507.06122

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 donโ€™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.
