Great job on this one. I've never been much of a sports fan myself, but from afar this has always frustrated me. Every time I go to the gym, it feels like I have to overhear the same debates.
As a kid, I used to always ask my musician father "who's the best musician" or the best this/that, and I always used to be disappointed when he'd cop out and just say "at a certain level of skill, there's really not much sense in comparing." Now I almost always offer the same answer when talking about "the best" anything.
Thanks for sending this one in, BM!
