Sandy, you seem to be against all the defensive metrics, but the correlation of UZR isn't too far off from the correlation of OPS.
If UZR is completely garbage, than OPS is a total garbage stat as well.
Its like calling ERA garbage and then using FIP (the correlations isn't that different).
Using SEVERAL defensive stats will give you much better picture of a player's defensive value than OPS will give you of a player's offensive value.
