The series is kind of light on details generally, but in this particular one I found Bauer's commentary fascinating, especially in light of what I've heard about him and Driveline and what my son's been doing (albeit at a completely different level) with similar analysis.
I lean to the analytic side myself, and I'm genuinely curious how this is going to play out over the next decade or two with baseball and the enormous amounts of data that can be collected (more and more easily and cheaply), and how that starts filtering down from the pro game.
