A first pass on my 2007 arm ratings for outfielders is now available.

That's a full listing of kills, holds and advances for all outfielders with at least one opportunity last season. I'd like to think that I'm following a simplified version of John Walsh's outfield ratings. I didn't capture events as distinctly as he did, and so my ratings should probably be taken with more than a few grains of salt.

Arm+ is a horrible junk stat. I am aware of just how awful it is. I was looking for a quick-and-dirty way to sort the list so that I could do a quick smell test and see how it was performing. The fact that Juan Pierre has one of the worst arm ratings -- even considering he's only compared to other center fielders -- gives me a warm and fuzzy feeling about the whole enterprise.

I'm looking for comments here (and from a few stats-oriented baseball sites I frequent) so that I can try and make some revisions to the system and have a better set of ratings out soon.
