At the end of the day, this is all about entertainment more than it is about baseball. That's true of all spectator sports - at the end of the day it's about pleasing a diverse fanbase that includes hard-core supporters who know the intricacies of the game and the average joe who doesn't know xFIP from UZR and doesn't care. A valid argument can be made that, for some parts of that fanbase, delving into advanced statistics enhances the entertainment value, and if this stuff does become more prominent in TV and radio broadcasts that will be the reason. I do think it would be possible, though, to apply them in a way that is more approachable for those who don't go to fangraphs regularly. Given a choice between hearing a) so-and-so has a poor xFIP, and so-and-so really relies on his defense to be effective, I think the second makes more sense for a larger fanbase.
