YADM: Defensive Regression Analysis
Take nothing away from Studes, Tangotiger, MGL, or Bill James; like the clock that keeps ticking, statheads keep coming out with new and interesting ways of assigning value to players. Unixphiles will immediately recognize in the title of this entry (YADM: Yet Another Defensive Metric) its kernel, and the acronym du jour is DRA, short for Defensive Regression Analysis. What makes Michael Humphreys' work so interesting is that he makes the claim that he only needs standard box score data to make his statistic go, unlike specialized and hard-to-get data needed for Zone Rating, UZR, and others. I haven't read all three parts yet (for simplicity, the original work can be found in part 1, part 2, part 3, the original BTF PDF, and this most recent series on The Hardball Times in part 1, part 2, and part 3), but that alone makes it look very, very appealing.
