It looks like Pitchers have to be included for the purpose of calculating wRC. This does though mean that a NL positon player with a league average wOBA is a below average hitting NL position player.

Are pitchers included in NL lgwOBA? If they are this would seem to me to be a mistake. What would be the point of knowing how a positon players hitting stacked up to a league average that included pitchers? This does bring another question to my mind though.

Per wRC and wRAA by David Appelman - December 12, 2008 http://www.fangraphs.com/blogs/index.php/wrc-and-wraa wRC - This is total runs created based of wOBA. It is calculated as (((wOBA - lgwOBA) / wOBAScale) + (lgR/PA)) * PA Evidently Bill James projects a lower lgR/PA then Chone even though he projects a higher lgwOBA then Chone. Thus in Bill James' projections Randy Winn will produce a lower wRC even though he has a higher wOBA and PA. I think I have found the answer to my question.

Per wRC and wRAA by David Appelman – December 12, 2008

wRC – This is total runs created based of wOBA. It is calculated as (((wOBA – lgwOBA) / wOBAScale) + (lgR/PA)) * PA

Evidently Bill James projects a lower lgR/PA then Chone even though he projects a higher lgwOBA then Chone. Thus in Bill James’ projections Randy Winn will produce a lower wRC even though he has a higher wOBA and PA.

For Randy Winn the three systems project the following: Bill James - PA 640, wOBA .340, wRC 73.8 Chone - PA 615, wOBA .336, wRC 78.2 Marcel - PA 599, wOBA .329, wRC 70.6 I can understand how Marcel's wRC projection is lower then Chone's since Marcel projects both PA and wOBA to also be lower then Chone. But, I can not understand how Bill James' wRC is also lower the Chone's since Bill James projects both PA and wOBA to actually be higher then Chone. Can someone explain this to me?

Chone – PA 615, wOBA .336, wRC 78.2

That post might even be able to include some rule of thumb pointers that generally explain the reason why the systems might differ on their projections of players I agree with Bryan.

Find the players in each system with the largest difference between their projections and Marcels projections and then try to deduce what the projection system knows that Marcels doesn't. If not helpful, it would at least be fun and interesting. It might make a very interesting post to talk about the differences between the systems.
