I don't play fantasy baseball anymore now because it's too much work, and I feel like I have to hold myself up to such a high standard. I'm pretty serious about my fantasy football, though.

There's always the risk that there are unknown unknowns.

It's a little strange to become a kind of symbol of a whole type of analysis.

I prefer more to kind of show people different things than tell them 'oh, here's what you should believe' and, over time, you can build up a rapport with your audience.

Walk rate is probably the area in which a pitcher has the most room to improve, but a rate that high is tough to overcome.

I don't think that somebody who is observing or predicting behavior should also be participating in the 'experiment.'

We want to get 80%-85% of predictions right, not 100%. Or else we calibrated our estimates in the wrong way.
