How’s My Driving: 2018 Top 100 Audit

I was hired as FanGraphs’ Lead Prospect Analyst just after the 2016 draft and took my first run at evaluating the entirety of the minor leagues on my own the following winter. Enough time has now passed that many of the players from that era of prospecting have had big league careers unfold (or not). Hindsight allows me to have a pretty definitive idea of whether my call on a player was right or wrong in a binary sense, and gauge any gap that may exist between my evaluation and what the player ultimately became. Looking back allows me to assess my approach to grading and ranking players so that I might begin to establish some baselines of self-assessment and see how I perform compared to my peers at other publications. Last offseason, I began compiling the various Top 100 prospect rankings from seven years ago for the purposes of such a self-assessment, an exercise that culminated in the “How’s My Driving?” piece that ran during Prospect Week 2024. This winter, I turned my attention to the 2018 Top 100, which I co-authored with Kiley McDaniel. Below are the results of that audit and my thoughts on them.
Before we get to a couple of big, fun tables and my notes, I want to quickly go over why I’ve taken the approach I have here and discuss its flaws. There are absolutely deeper avenues of retrospective analysis that can be done with prospect lists than what I have attempted below, approaches that could educate us about prospects themselves, and probably also about prospect writers. (Last year, in the first edition of this piece, I proposed a few such potential methods of evaluation and included my thoughts on their limitations. For the sake of brevity, I’ve cut that discussion from this year’s edition, but if you’re curious about that stuff specifically, you’ll want to go back and read the paragraph that begins, “Eventually, someone could pool the lists…”) Read the rest of this entry »
