I'd give him the benefit of the doubt, but google indicates that in August 2012 they were apart by at least 1 WAR. Maybe before then that they were even or Barney was ahead.
Either way, I find it funny how quickly you have come to the defense of WAR when that (and many other examples) show that it is still flawed in some glaring ways.
edit: Alright I looked at an article and he may have got his names mixed up. Barney tied war with Votto and Posey. Not exactly Miguel Cabrera, but he still doesn't belong in those discussions.
