Just so I am completely sure I understand your argument...
You are claiming that the stathead that invented WAR (a universally accepted stat), is somehow on the same level as some forum idiot that claims "only OBP matters"? You can't see a difference between these two people, they are both just statheads? If I accept what the inventor the WAR claims, I must also accept the forum guy's opinions?
And yes, anyone that claims "only OBP matters" is wrong.
