UZR 2003-2008

MGL provided me with his 2003-08 UZR, but I’m only allowed to provide limited views to that data.  Here’s some of what I’ve got:

The run value I provide has been altered to account for the position differences.  And I put it against 500 “BIP”.  I use the BIP per game:
pos BIP adj
2 0 12.5
3 2 -12.5
4 4 2.5
5 3.5 2.5
6 4.5 7.5
7 2.5 -7.5
8 3.5 2.5
9 2.5 -7.5

Everett for example is +28.1 per 500 BIP, which would translate, for a SS to 41.0 runs per 162 G.  I give all SS a 7.5 run bonus (the ADJ column above), so that his “original” UZR would be reverse-engineer as 41 minus 7.5 or 33.5 per 162 G. 

His “original” UZR is actually +121 (!!) runs in 585 G, or 33.5.

Finally, I apply a regression by adding 400 BIP of average fielding.  Here are the lists, minimum 120 games, for best/worst infielders, outfielders, firstbasemen:
