Magic Maddux

ESPN the Magazine has a cool piece on Greg Maddux. Maddux has been written about a ton, but I did get a nugget or two that I hadn't heard before. The one that's stuck in my head: he some times changes pitches in the middle of his windup! He's not just being indecisive, he adjusts based on the batter's stance. Does anyone else do this? I realize not everyone can, but does anyone try? How many pitchers have even thought to?

Can we inject Maddux's pitching intelligence into every other pitcher and see what happens? How fun would a Maddux-Verlander hybrid be. Someone get on that.
