A decade after Baseball Prospectus let Voros McCracken spread the gospel in a story that popularized DIPS across the sport, it remains among the most seminal theories developed by sabermetrics, the nickname given to quantitative baseball study. It’s almost certainly the most revolutionary. Nothing before or since has so upended an entire line of thought and forced teams to assess a wide breadth of players in a different fashion. Of course, one great idea guarantees nothing. McCracken lives paycheck to paycheck. He couldn’t make rent on his apartment last year.
