Holy crap! Can u save me some time and explain how this was arrived at and the usefulness of this in evaluating player contribution? What are good numbers, avg, and poor? I know how my players rate but not totally sure what the numbers mean. I can say I'm not surprised when I see who is highest and who is lowest however. It does seem the kids who played in fewer games score significantly lower on this stat which causes me to wonder how useful this metric is.

We don't know the ins and outs of it. It was created by Bill James who has created many of the metrics players are rated on. If you click the Wikipedia link from that page, it gives some more details.

Actually the formula attributed to Bill James on Wikipedia is significantly less complex

Our understanding is that all the variations presented are Bill James' creations, and the "technical" one just provides a more accurate number based on his thinking.

Ok I see that version now. I do find it interesting that neither PA w/ RISP or actual runs scored appear to factor in.

The technical version looks like it's based on "runs created" per plate appearance, so games played should not factor in, but that's what I see too. Also, not only does RC not account for actually scoring (nor RBIs), it doesn't account for being able to score from 2nd on a single. We have players who never score from 2nd on a single and one who does it just about every time. The ones that do are scoring and creating a lot more runs than the ones that don't. Also, elite, aggressive baserunners can score from 3rd on passed balls/wild pitches where others can't. Bill James was thinking of MLB where scoring from 3rd on a pitch is relatively rare, but even there, guys who can score from 2nd are surely "creating" more runs than guys who can't. What say you, Bill James?
