More trivia than stats. That is a distinction Silver was big on in his first incarnation as sports statistician, and he got huge pushback from it. Nobody in traditional baseball commentary wanted to talk about VORP, say, and they certainly didn't want to root their commentary in solid statistical analysis. Traditional baseball use of statistics (I mainly follow baseball) has been very much of the trivia variety: this is the first time a right-handed batter has has two hits in the same inning against a left-handed pitcher while the wind is between 12mph and 15mph on a Tuesday. Not so much about backing up your opinions with solid predictive statistics.
