There&#8217;s no in between. The metric varies &#8212; sales, monthly active users, whatever is core to the business. But the same principle applies to the <em>capability</em> of the group itself, and this is just as true in modern MLB front offices.</p><div class="pullquote"><p>Why does growth matter so much?

Lag, acceleration, exponential growth &#8212; and then, without the right conditions to sustain it, retardation, stasis, and death. Analytics departments are no different.</figcaption></figure></div><h2>Hiring</h2><p>New people bring new ideas &#8212; new ways of thinking about old problems, and new problems worth thinking about. This effect compounds when the hire is either coming from another organization or operating at a senior level. There is real, underrated value in someone who has simply been there and done that &#8212; who can say with confidence, <em>&#8220;when I was at XYZ, we solved it like this.&#8221;</em> Maybe that method is outdated or doesn&#8217;t translate perfectly. But the knowledge is valuable, and the pattern-matching is faster than building from scratch.</p><p>The problem space an analytics department owns is also just enormous. Everything from pitcher injuries to Korean player projections to when to bunt to optimizing third base coach decisions on tag-up plays. Some of these are large efforts; some are niche. Not every problem warrants a dedicated person. But there is a baseline headcount below which you simply cannot cover the surface area.</p><p>And that surface area is only expanding. Biomechanics exploded. Teams now have pitching and hitting motion capture labs. Torpedo bats became a thing. Teams ship their own internal mobile apps. Other internal departments &#8212; player development, medical, strength and conditioning &#8212; are rightly asking for more analytical support, and the nature of that support has become significantly more sophisticated.</p><p>In the good ol&#8217; Moneyball days, you could mostly ignore the S&amp;C coach and they&#8217;d be frustrated, but not dangerous. Today it&#8217;s different. Because one thing that is assuredly worse than a frustrated S&amp;C coach is a frustrated S&amp;C coach with just enough programming knowledge and access to Claude.</p><div><hr></div><h2>Expanding Scope</h2><p>Growing the scope of what the department owns is distinct from simply hiring more people to do existing work. This is about deliberately moving into adjacent problem spaces &#8212; building new capabilities rather than deepening existing ones.</p><p>Player development is a clear recent example. The analytics departments that stayed in their lane &#8212; draft models, game strategy, roster construction &#8212; ceded enormous ground to organizations that pushed into development earlier and more aggressively. Medical and strength and conditioning could be next. The teams treating those as purely human-judgment domains are leaving data on the table. There are many frontiers beyond this that are partially or barely explored.</p><p>The discipline here is prioritization. You can&#8217;t own everything, and trying to spreads the department too thin. The question isn&#8217;t <em>should we expand</em> but <em>where should we expand next, and in what order.</em></p><div><hr></div><h2>New Tools &amp; Technology</h2><p>Computer vision models are genuinely useful &#8212; but not trivial to implement. Compute is now effectively free &#8212; but leveraging it well requires deliberate investment. Trajekt, new bat designs, mental skills platforms, vision training, sports nutrition, bone density testing for projecting young Latin players&#8217; development &#8212; all of it is becoming more powerful, generating more signal, and creating more opportunity for the teams willing to engage with it seriously.</p><p>The risk is insularity. The tools that will matter most in five years may not be coming from inside baseball. They&#8217;re being built in other domains &#8212; medicine, defense, consumer tech &#8212; and the organizations that are scanning broadly and adapting quickly will have a structural edge over those that are only watching what other teams are doing.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank"

I learned so much during my time in the organization. And now the distance has given me a new perspective. Some things you can only see once you&#8217;re on the outside. Others just come into sharper focus when you&#8217;re forced to articulate them. Looking back, I learned a lot of lessons along the way &#8212; I just didn&#8217;t know it at the time.</p><h2>I&#8217;m not bitter</h2><p>I loved my time in the org. I met great people - players, coaches, data scientists, scouts, lunch ladies - more people than I can name. Many of the people are still my best friends. My experience was a great one - I&#8217;d do it all again. </p><p>The &#8220;bitter&#8221; actually is a nod to the great Richard Sutton&#8217;s Bitter Lesson. While there will inevitably be longer posts on this topic, it states briefly that instilling human knowledge into computational systems to help solve problems may help in the short term, but will inevitably be far surpassed by systems that effectively leverage search and learning. The bitterness is in what it takes away: the clever human insight, the hard-won intuition, displaced by scale. Yet for me, there&#8217;s something magical in that. The bitter lesson is the ingenuity in the system.</p><h2>So what&#8217;s next?</h2><p>If I were running an analytics department in an MLB front office today, this is how I&#8217;d try to do it. Some posts will be technical. Some will be about structure, culture, and organizations. Some will just be whatever I&#8217;m thinking about.
