What are the key takeaways from this Odd Lots episode?

Key insights include: **Data Censoring for Irregular Game States:** When analyzing player performance, remove data from matches with extreme game states — such as a team reduced to nine men — to avoid skewing seasonal metrics. A single anomalous match, like Nicholas Jackson's three-goal game against nine-man Tottenham, can represent roughly 20% of a player's entire season goal output.; **Expected Possession Value Models:** Move beyond expected goals (xG), which only registers value at the moment of a shot, by using expected possession value models that calculate the probability of scoring within the next 30 seconds of any possession. These models identify momentum spikes and can be used to surface specific video clips for coach review.; **MLS Portfolio Management Framework:** MLS salary cap rules create a three-vector analytics challenge — recruitment, first-team analysis, and portfolio management. Each roster slot carries a designated cap charge rather than actual salary, so player value must be assessed relative to slot cost, similar to allocating capital across asset classes with different risk-return profiles.

What did Joris Bekkers discuss on Odd Lots?

Soccer analytics consultant Joris Bekkers and volatility arbitrage trader-turned-risk executive Mike Tracy explain how tracking data, neural networks, and expected possession value models are transforming football recruitment, in-game strategy, and player evaluation — drawing direct parallels to derivatives trading frameworks and portfolio management theory.

Key Takeaways

✓Data Censoring for Irregular Game States: When analyzing player performance, remove data from matches with extreme game states — such as a team reduced to nine men — to avoid skewing seasonal metrics. A single anomalous match, like Nicholas Jackson's three-goal game against nine-man Tottenham, can represent roughly 20% of a player's entire season goal output.
✓Expected Possession Value Models: Move beyond expected goals (xG), which only registers value at the moment of a shot, by using expected possession value models that calculate the probability of scoring within the next 30 seconds of any possession. These models identify momentum spikes and can be used to surface specific video clips for coach review.
✓MLS Portfolio Management Framework: MLS salary cap rules create a three-vector analytics challenge — recruitment, first-team analysis, and portfolio management. Each roster slot carries a designated cap charge rather than actual salary, so player value must be assessed relative to slot cost, similar to allocating capital across asset classes with different risk-return profiles.
✓Tracking Data Structure for Neural Networks: Positional tracking data captures x-y coordinates for all 22 players at 10–25 frames per second, while skeletal body pose data adds 27 coordinate points per player — roughly 27 times denser. This data enables neural networks to quantify off-ball movements, defensive lane closures, and positional value that on-ball event data entirely misses.
✓Analyst-as-Translator Layer: The primary bottleneck in applied soccer analytics is not model quality but knowledge translation. Effective implementation requires a dedicated data analyst who converts model outputs into curated video clips for coaches, since raw model outputs are not directly actionable by coaching staff and halftime or quarter-break windows are the realistic adjustment points.

Notable Moment

When asked whether soccer could ultimately be reduced to computation like chess, Bekkers described how an initially overwhelming stream of continuous coordinate data becomes manageable once discretized into two-to-three-second micro-events aligned with on-ball actions — suggesting the beautiful game may be solvable through sufficient data density.

At IBM, we work with our employees to integrate technology right into the systems they need. Now a global workforce of 300,000 can use AI to fill their HR questions, resolving 94% of common questions. Not noise. Proof of how we can help companies get smarter by putting AI where it actually pays off, deep in the work that moves the business. Let's create smarter business. IBM. When you're running a business, the best days are the ones where priorities stay on track. For midsize and large companies, that isn't always easy. Risk can touch multiple parts of an organization at the same time, often in ways that aren't immediately obvious. It might involve property, liability, or cyber. It could stem from regulatory requirements or challenges tied to a specific industry or the scale of an operation. At that level, managing risk becomes an ongoing discipline, not a one time decision. At The Hartford, the focus is on helping businesses manage risk before it turns into something more disruptive. That means working with companies to identify where they're exposed, decide what matters most, and put practical standards in place so risk is managed as part of day to day operations. And when losses do happen, The Hartford can pair that risk control work with insurance coverage grounded in underwriting, risk engineering, and claims experience developed over time.

Tracy, I have a question. I know you spent a lot of your youth overseas. My youth. Yeah. You. Right here. Did you ever go to many baseball games as a kid? Yeah. So I was in Chicago for a few years. Yeah. So I went to the Cubs games, and then I was in Japan. And the baseball scene in Japan is amazing. Like, the best vibes of a live sports event that I've ever ever witnessed or encountered. I was just talking to someone about this last night. I've always wanted to go to a Japanese baseball. Highly recommend. Say, like, if we ever do a live show in Tokyo, let's try to schedule it during baseball season because that is, like I sort of think that's a bucket list thing. But, anyway, the reason I asked this question is I have this really vague memory as a child going to see Detroit Tigers games with my grandfather, like, probably when I was, like maybe these memories are probably from when I was younger than, like, six or five. Mhmm. But there used to be a nontrivial …
