I'll disagree with this. I've always liked baseball, but didn't really get fully into it until more of the stats stuff became mainstream and it really appealed to the scientific side of my brain. I think it does take a certain mindset to enjoy it though, especially if you didn't play a lot growing up. Baseball is really the one true team sport that lends itself well to advanced individual analysis, since so little of a player's game is really other- or team-dependent (R, RBI, E).
