Today BP is allowing a free preview of their site. If you have never subscribed, now is a good time to see if it would be worth it. After not having it for awhile, this preview is making me realize what I've missed.
Oh and make sure to check out their coverage and anaylsis of the deadline deals.
http://www.baseballprospectus.com/Most of our content is only available to those with a Baseball Prospectus Premium subscription. From July 27 to August 3, however, everyone can access the great baseball content and stats that subscribers get year-round.
