Yes, those are hard to measure. What is not so hard to measure is OPS, WAR etc. We have a problem offensively, and unless a new infusion of talent at 3B, our major problem, is found, we will need to address it in other ways-and adding Avila would be a very good way to deal with it. Our catchers are both bottom third in most offensive categories. I would trade their unmeasurable defensive stats for more offense in a heartbeat.
