I'm not convinced that sabermetrics is a supplanted terminology -- the links that you provided actually make use of the term, although since its origins are in baseball that may explain why other sports want a different terminology. And, of course, there already exists Baseball-Sabermetrics.
Having essentially two top-level names (Algorithm::SportsAnalytics::TheModuleName) strikes me as wasteful in space. I'd go to the module-authors list and suggest a single top name like SportsAnalytics and see how it flies.
If SportsAnalytics doesn't work, then maybe an offshoot of Statistics (e.g., Statistics::Baseball::Analytics)?
