View Full Version : Buster Olney, Defense, & my favorite chart

Over at THT, there's an article about the current state of defensive analysis in reaction to a post by Buster Olney which was also quoted here. Here's the article: http://www.hardballtimes.com/main/article/educating-buster/

One of things I love about it is the chart used about 2/3 of the way down. In my mind it's brilliant -- Edward Tufte would be proud. Anyways, check it out -- especially those looking for some more background on defensive stats.

I don't know how you guys feal about the validity of the data being presented in the charts RMR refered to, but I'm working from the assumption the data is valid.

Those are VERY helpfull charts for me (1) I am very visual (2) they break the information down in digestiable chunks instead of entire computer screen of numbers.

Many thanks to RMR. Would love to see said charts on various reds players.

Well...depending on the player...maybe I wouldn't.

I would love to see the red line weighted in thickness based on the number/percentage of balls fielded in that vector. Otherwise, Jeter's massive deficiency going to his right looks worse that it is in practice.

Of course, this would also mean more if you showed ARod. Perhaps Jeter is shading his left because he knows ARod has good range and will help cover him. Graph those two on the same X-Axis and see where the Yankes are collectively weak.

I wouldn't mind picking up Adam Everett. I don't know if i believe in a synogystic effect, but i wonder if the pitchers become more aware of throwing the ball low when you have a SS like this. Seems lie you could pick him up for a low price -defensive stats are often considered not valid (as mentioned in the article). But if you could really believe in such a thing --couldn't you make the case that Everett is an above average SS?

2 years ago GABP's grass slowed down ground balls in a big way ---it really was a neutral park because of the high grass in the infield. Is the grass still as high? I'm guessing not.

That's some solid stuff. Thanks for posting it, RMR.

So if I'm reading the cool little color charts correctly, it basically confirms my belief that Derek Jeter is a highly overrated that deserves no Gold Gloves, and Adam Everett is a lot better than I ever knew.

My only question is how much do other fielders influence the outcome of these results? Since PayRod joined the Yankees, Jeter can shade himself more up the middle at SS since he knows #13 can essentially cover his butt on balls in the hole. I suppose the same could be said for the 2B/1B side of the field, but I think you'd see more influence from a 3B helping the SS.

A lot of the good defensive metrics take into account things like the player playing next to him, the slowness of infield, the number of lefties on squad...heck the Baseball Fielding Bible watches every play on video tape. It ain't like they are guessing.
