Great story by Lee Jenkins in the New York Times.
There's the mean Randy:
Around Major League Baseball, he is considered a gruff and cranky character, as likely to scowl at a teammate who interrupts his pregame routine as he is to buzz a hitter who gets too comfortable in the batter's box.
And there's the nice Randy too. But mostly, you get the sense that there is a driven, committed Randy Johnson at the bottom of it all.
