I strongly recommend reading this. I was trying to get it to load to link last night, but it wouldn't. Now it will. It's very good, featuring comments from Greg Maddux, Pete Smith, Jim Bouton, Mike Remlinger, John Rocker (!), Syd Thrift (boooo!), Tom Glavine, Hank Aaron, and others.
It will learn you all you wanted to learn about Leo.
