So does MGL sell his data to teams? The most current UZR numbers are usually not available to the public (other than the best-and-worst highlights), so I’m curious why he’s giving his formula to Fangraphs. Maybe he has more in-depth stuff that is still proprietary?
Fangraphs’ UZR doesn’t include throwing arms yet. Cardinals fans tell me his range really suffered after the injury. ANKIEL is why you think UZR is crap?
If you’re thinking that team UZR should match team DER, not quite. DER needs to be park-adjusted, for one. For two, maybe the hitters happened to hit a lot of balls that were tough to field.
My uneducated guess would be that RZR has more variance and less agreement with other defensive metrics like UZR, PMR, and the +/- system, and as such should be disregarded, though I have absolutely no idea if this is the case or not.

Saw that today. Very cool.

UZR + BIS data
= Ichiro as a plus defender
baetown415 - December 7, 2008
Ibanez was 6th in defensive games last year
Mariner John - December 7, 2008
As a RF back in '04
Ibanez projected to be -130 runs on the year. It was only 18 innings, but boy… they must have been something.
Bearskin Rugburn - December 7, 2008
Hey, Brad Hawpe is bad.
Teej - December 7, 2008
I noticed that one too
Jeff Sullivan - December 7, 2008
Apparently Rick Ankiel blows at defense
UZR : defense :: flat earth society : geography
JI - December 7, 2008
Are you serious?
Fangraphs’ UZR doesn’t include throwing arms yet. Cardinals fans tell me his range really suffered after the injury. ANKIEL is why you think UZR is crap?
Sky Kalkman - December 8, 2008
It's a joke.
JI - December 8, 2008
He's one of those guys I always think, "I know he's either really good in the field or really bad. I can't remember."
So now I know the answer to that.
Teej - December 7, 2008

Reminds me of one of my favorite Bill James quotes
Re: Ryan Klesko
“As a leftfielder, he’s a firstbaseman”
JI - December 7, 2008
The name just says "oaf" to me
Jeff Sullivan - December 7, 2008
I've never met a cool person named Brad.
And when I hear the name, all I think about is that douchey fantasy “expert” on Yahoo whose entire area of expertise is name puns.
Teej - December 7, 2008
I wrote that entire comment thinking this was the Wilkerson post.
And yet the point remains 100% the same.
Teej - December 7, 2008
I love his name because I gives me to overpronounce the "W" in hop.
JI - December 7, 2008
You know what I mean
JI - December 7, 2008
what
JLC - December 7, 2008
I'm sitting on an awesome pun and just waiting for the opportunity to strike
Jeff Sullivan - December 7, 2008
I look forward to it.
I, for one, always thought they were funny in small doses.
At work, I want to stab people when they do it because it looks so childish and ridiculous in a newspaper, but here, I love it.
Teej - December 7, 2008
I Hawpe it comes soon
Graham MacAree - December 7, 2008
Just tell us already!
JI - December 7, 2008
If you'd Wakamatsus for one day you'd see how important it is to enjoy the little things like this
Jeff Sullivan - December 7, 2008
I refuse to believe that Fogel didn't hack your account.
JI - December 7, 2008
Plus, when that turns green I'm going to flag it
so my love and hatred can be expressed visually
JI - December 7, 2008
That took me a full 30 seconds to decipher.
Ridiculous. And hilarious.
Teej - December 7, 2008
Again with the fucking puns
ugh I thought we were done with them
Dewey N - December 8, 2008
You spelled Dunn wrong.
Too easy, I know.
Teej - December 8, 2008
it's interesting that only 60 players posted a UZR of
0.0 or greater last season.

sirbrianwilson - December 7, 2008
Are you sure you weren't limiting the leader board to qualified players only?
Sky Kalkman - December 8, 2008
Hey Marcels and Bill James' projections
My week is now shot.
JI - December 7, 2008
Stephen Drew almost as bad as Yuni?
What?
Goose - December 7, 2008
Only by this measure
PMR thinks he’s a little below-average and he doesn’t show up in the +/- best/worst lists.
Jeff Sullivan - December 7, 2008
RZR doesn't like him much
Jeff Sullivan - December 7, 2008
RZR should probably go away now
There’s no reason to ever use it again. It’s based on the same dataset as the UZR at FanGraphs, and it’s not nearly as accurate.
davidcameron - December 8, 2008
Is UZR going to be part of the daily in-season update?
Jeff Sullivan - December 8, 2008
Weekly, I believe
Bearskin Rugburn - December 8, 2008
Accurate?
How does one define accuracy wrt defensive metrics?
Graham MacAree - December 8, 2008
Are player run values fitted to the team defensive value?
If not then you could compare the sum of the player run values to the total team value. Team defense is easier to predict right?
Edgar for Pres - December 8, 2008
Why is team defense easier to predict?
If you’re thinking that team UZR should match team DER, not quite. DER needs to be park-adjusted, for one. For two, maybe the hitters happened to hit a lot of balls that were tough to field.
Sky Kalkman - December 8, 2008
Maybe precision is a better word?
My uneducated guess would be that RZR has more variance and less agreement with other defensive metrics like UZR, PMR, and the +/- system, and as such should be disregarded, though I have absolutely no idea if this is the case or not.
JLC - December 8, 2008
bUZR and STATS ZR combo?
sUZR still isn’t public and based on what MGL’s reporting on the correlation of bUZR and sUZR, we need to use a STATS-based metric, too.
