I found this blog post by Gabe Kapler to be really interesting:
Full Count » Stats 101: Why it?s time to re-educate players in meaningful statistics

If, as a player, you know your FO is very much into advanced metrics, does that mean you view your performance differently?

What happens with someone like Perkins who is into advanced stats -- seemingly more than the team he plays for.

I also liked the comment about wanting more stats during games since that's something we've discussed elsewhere in these forums.

Overall I thought it was an interesting read and that it also threw a bit of light on what players go through during "bad" streaks.
