Here's the thing that has always bothered me with this discussion, and you can almost compare it to the "battle" between bloggers and mainstream media members. No statistician thinks that scouts or scouting department needs to be replaced. Just like bloggers think that mainstream media shouldn't be rendered obsolete.
Sabermetrics is really just another way to gather information, and I really don't think a team that utilizes it, is completely basing their decision on just the stats. To think that a team would draft a player, without seeing him play or watching tape, is just ignorant.
You have to commend the MLB Network for trying, but if you don't really know anything about the topic, it's best to just stay away. Much like me talking about MMA.
