Ok, and they are right 100% of the time?
See, if anyone can't make a point without turning to fundamentally flawed equations, that's their problem.
Explain to me why teams have scouts, if the numbers are all you need.
Let me give you an example of how ridiculous you guys sound.
Chris Coghlan is better than Ryan Braun. Why? Coughlan his .321, and Braun hit .320. NO DOUBT ABOUT IT. He's better. Who cares if you watch the gamezzzzzzzzzzzzzzzzzzzz? He's better. Look at the batting averages!
This is where we are in defensive matrices. We aren't even advanced to the point of batting averages. Today, we have OPS, OPS+, WAR, and so on and so on. Our knowledge and understanding of the game has increased dramatically. In the 60s and 70s, teams used batting average almost exclusively to determine a player's value, with little or no value given to OBP.
The sheep who are braying for UZR will be eventually be shown to have been barking up the wrong tree. Why? An inability to QUESTION what you read, and to blindly follow without circumspection.
