A while back I mused on converting player VORP by position to see what a player might be worth at a different position. For calculations I used the formula stated by hentler a few diaries ago. It's not perfect, I checked the calculated VORP against the "official" VORP from BPro. Most were close (Joe Mauer) but some were pretty off (Granderson, Sizemore). I'm not sure where the discrepancy comes from.
Anyway, I've got the basic functionality of the little tool down. There's plenty of bugs in the cosmetic function, and it looks ugly, but it works. It also displays comparable VORP scores of players at the "new" position (so if you move Granderson to 1B, it will show his 1B VORP compared to his CF VORP, and then will show the 1B players with the most similar 1B VORP scores). So far, this is 2006 data only. I'll work on other years at some point.
Oh, batting VORP only.
