And I think the RS-RA equation can give one an indication of overall-ness. But I don't think it's a good indicator, is incomplete, when trying to breakdown/evaluate a player's offensive or defensive capabilites. Those, somehow, need to be broken down and looked at separatley to get an accurate "picture" IMHO.It would be very interesting do some RC analysis on the whole league, including defense, and just show the rank of Reds starting position players across the NL. The overall point being made is that while Junior (and Dunn for that matter) are both solidly above average offensive players, their below average defense tempers their overall value in the RS-RA equation.
And I am a huge skeptic at those defensive matrix that currently exist. I relaize that is all we have at this stage, but again, I think they are not a solid/reliable gauge.
With Runs Allowed - how is it charted? How is it determined what criteria must be met to classify a situation as "runs allowed"? Is it a group of guys sitting around charting balls hit into the OF (zones), and where run(s) are scored, subjectively saying "That ball should have been caught"? Or does it only qualify if the OFer commits an error on the play which allows run(s) to score? What is the criteria?

"panic" only comes from having real expectations
Currently metrics such as RC or VORP estimate his true offensive value and PBP based metrics give the best picture of a player's true defensive value. A player's offensive and defensive abilities ARE determined separately. However to understand a player's true value, he must be evaluated by considering BOTH in concert-it's the sum of a player's defensive and offensive value that represents his effect on his team's run differential.
While traditionally estimating the offensive side of things was much more accurate than the defensive side of things, the defensive side is rapidly advancing. What's more, major league FOs are viewing players through this new prism since defense followed OBP as the market inefficiency that teams pounced upon.
