Just realized that we don't have similarity scores and that would be a neat add:

By this, I mean similarity scores within a universe, ideally also for "most similar at age X" scores. Behind the scenes you'd have to compile career and career-to-age records for everyone any time you ran this (so maybe you'd only update them once a year) but this would be a really neat way to contextualize players (and now I'm thinking about how to do this in my own universe).
