My mind is blown right now. I always figured that, since at least the 1970s, 30 MLB teams and their 2,430 games were plugged into some sort of algorithm in a Deep Blue computer somewhere and spit out into a perfect mesh of baseball. But nope. Up until 2005, it was done with pencil and paper by a husband and wife in New York.

ESPN released their latest 30 for 30 short, The Schedule Makers, on Henry and Holly Stephenson, who, for over 20 years, compiled the MLB schedule on their kitchen table.

For the last eight years, the schedule has indeed been made by a supercomputer, which, as Holly explains, is why you get Mariano Rivera ending his career in Houston. Or, perhaps, why the Phillies opened their season at home against the Royals.

Must-watch after the jump.
