It’s not a stretch to say that BP has totally altered the baseball landscape, and that its influence on the game, both in front offices and in the media, is bone-deep. It’s also fair to say that this influence has created the conditions for its own obsolescence.
The proliferation of BP’s values has made the site far less revolutionary than it once was. The use of statistics in both front offices and the press is now the norm, not a subversive approach to the sport. Not only does the site have a significant direct competitor in FanGraphs, which also offers projections and prospect coverage along with a statistical inventory similar to that of Baseball Reference, but every mainstream outlet at least nods in the direction of analytics.
