NPB, KBO and the ever fascinating for me topic of why japanese do insist on the "typical japanese swing" (as opposed to a "major-league swing")?

Baseball's Billion Dollar Equation
In 1999 Voros McCracken infamously speculated about the amount of control the pitcher had over balls put in play. Not so much, as it turned out, and DIPS was born. It's tough to put a value on something like DIPS, but if an MLB team had developed and exploi...

I love your data science series. And here it's really starting to get interesting.

But I'm not sure where the "$200M surplus" came from when you said, "An 8th round draft pick like Paul Goldschmidt could net you a $200M surplus."

It would seem to be the difference between what the player is paid and the amount of revenue he brought in. I see that his price tag for Goldschmidt is $32M for 5 years (2014 to 2019). His value, according to the table at the bottom of the page you pointed to, has been $71.4(M?) from 2011 to 2014. So are you projecting his value to increase at a much higher pace over the next several years? And the point, that I missed, is that it's the job of the data scientist to come up with methods of accurately projecting such players?

Thank you again for sharing this knowledge.

Thank you for this list. The only part missing is how to find the time to pursue all of the things I want to learn (a completely different problem).
