As you can see in this video, Maddux was always a bit coy about what made him so good. It was like he had discovered this great mystery but needed to keep it to himself. Teammates often talked about his encyclopedic knowledge of opponents or his ability to read into a batter's body language, but Maddux always played this down. I remember interviewing him once and asking something along those lines and he simply joked, "Well, if I told you I'd have to kill you." He then took a baseball and showed how he would change his grip or finger pressure for different pitches, but he had such a big smirk on his face that to this day I think he was simply screwing with me.
I remember seeing interviews like this when he played. It would be amazing to see him talk about baseball, anytime you saw him off the field, in the dugout or whatever, he was messing around. Then he's just genius level thinking on the field. I remember watching him pitching like a 2 hitter in the 6th or so one time. They show him in the dugout and he's standing in front of a couple of people practicing his golf swing. So hilarious.
