If you haven't subscribed to Baseball Prospectus yet, you should do so today. I've always been a big fan of the Baseball Prospectus Annual books, but have always resisted buying the subscription to the web site.
When my friend Dan became a BP author and started writing a weekly column, I decided to take the plunge and subscribe.
Not only am I able to read all of Dan's columns, I'm also finding a wealth of other information that I didn't realize was there. It's a great resource if you are at all interested in baseball and analysis.
